did the three gorges dam collapse

[12] Among those 32 main generators, 14 are installed in the north side of the dam, 12 in the south side, and the remaining six in the underground power plant in the mountain south of the dam. The flood affected more than 2.3 million people, killing 1,526. When the dam first began operations, China’s state media made grand claims that the dam can withhold the worst flood in 10,000 years. Experts are concerned the Three Gorges Dam is in danger of collapse due to a combination of the volume of rain failing and satellite photo's comparing the dam between 2009 and 2019 that indicate the dam has warped since it's construction. It is conjectured that this could have extreme cascading effects, involving 16 nuclear power plants downstream. Three direct current (DC) lines to the East China Grid carry 7,200 MW: Three Gorges – Shanghai (3,000 MW), HVDC Three Gorges – Changzhou (3,000 MW), and HVDC Gezhouba – Shanghai (1,200 MW).

FB.init({ Located in Sandouping (三斗坪), Yichang City, Hubei Province, 38km from Gezhouba Water Control Project at the downstream, Three Gorges Dam is the main work of Three Gorges Project, which is the largest hydropower project in the world. [73][74], The Three Gorges Dam reached its design-maximum reservoir water level of 175 m (574 ft) for the first time on October 26, 2010, in which the intended annual power-generation capacity of 84.7 TWh was realized. [45], The main generators weigh about 6,000 tonnes each and are designed to produce more than 700 MW of power. [93] This region has long been known for its rich biodiversity. The project used 27.2 million m3 (35.6 million cu yd) of concrete (mainly for the dam wall), used 463,000 tonnes of steel (enough to build 63 Eiffel Towers), and moved about 102.6 million m3 (134.2 million cu yd) of earth. About 32 landfills were added, which could handle 7,664.5 tonnes of solid waste every day. The power plant of the dam project was completed and fully functional as of July 4, 2012,[10][11] when the last of the main water turbines in the underground plant began production. On completion, the reservoir flooded a total area of 632 km2 (244 sq mi) of land, compared to the 1,350 km2 (520 sq mi) of reservoir created by the Itaipu Dam. fjs.parentNode.insertBefore(js, fjs); The collapse of the TGD would perhaps be the single largest disaster that could affect the world’s food security because aside from the immediate disaster there would be enormous upward pressure on food prices, putting essential staples out of reach of hundreds of millions of people outside China. [22][23][24][25], A large dam across the Yangtze River was originally envisioned by Sun Yat-sen in The International Development of China, in 1919. The trials of elevator finished in July 2016, the first cargo ship was lifted on July 15, the lift time comprised 8 minutes. [7] After the extensive monsoon rainfalls of 2020, the dam's annual production reached ~112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016. [77], Power distribution and transmission infrastructure cost about 34.387 billion yuan. The Three Gorges Dam was designed to tame China's longest river. In addition, populations of the Yangtze sturgeon are guaranteed to be "negatively affected" by the dam. [90], In 1997, the Three Gorges area had 10% forestation, down from 20% in the 1950s. Each of them is made up of five stages, with transit time at around four hours. "Slight deformation" on some peripheral parts of the structure was reported by local media last week. Concerns are rising that China's Three Gorges Dam, the world's largest dam, could be on the verge of collapse triggering a devastating 250-foot tidal wave that would wipe out cities, reported The Sun. }); [83], There are two series of ship locks installed near the dam (30°50′12″N 111°1′10″E / 30.83667°N 111.01944°E / 30.83667; 111.01944). [89] Also, in the first four months of 2010, there were 97 significant landslides. [78], Power is distributed over multiple 500 kV transmission lines. [91] Over one billion tons of wastewater are released annually into the river,[85] which was more likely to be swept away before the reservoir was created. The official Xinhua News Agency quoted the operator of the the world’s largest hydroelectric gravity dam as saying that some nonstructural, peripheral parts of the dam had buckled. That is a significant change from the 13,000 km2 (5,000 sq mi) net loss of forest each year in the 1990s. A flood alert has been raised near Three Gorges Dam in China-- the largest hydropower project in the world-- as the country grapples with its worst flooding in 70 years. [16][36] The dam had raised the water level in the reservoir to 172.5 m (566 ft) above sea level by the end of 2008 and the designed maximum level of 175 m (574 ft) by October 2010.[37][38]. The ship lift must work even if water levels vary by 12 meters (39 ft) on the lower side, and 30 m (98 ft) on the upper side. ", "NASA Details Earthquake Effects on the Earth", "39.1931, 1935, 1954, 1998 年长江流域发生的4次大洪水造成了怎样的洪水灾害?? However, damage to the entire dam through means such as missiles could cause flooding along a large area of the Yangtze River due to overflow spillage.[143]. China regards the project as a monumental social and economical success,[17] with the design of state-of-the-art large turbines,[18] and a move toward limiting greenhouse gas emissions. The technology transfer agreement was signed together with the contract. [16][122] Lahmeyer, the German firm that designed the ship lift, said it will take a vessel less than an hour to transit the lift. The problem is that China once claimed the dam would withstand a 10,000 year flood, then a 1,000 year flood and now only a 100 year flood. Average efficiency is over 94%, and reaches 96.5%. Completely interpretation their picture within the Tv set play, the eternally Piaget duplicate wrist watches with. Another eight dams are in the midstream of the Jinsha and eight more upstream of it.[150]. Th photo, taken on August 17, 2020, shows water gushing out from the Three Gorges Dam in southwest China's Chongqing province. Groups of craft would be lifted together for efficiency. At current levels, 80% of the land in the area is experiencing erosion, depositing about 40 million tons of sediment into the Yangtze annually. [30] Some exploration, survey, economic study, and design work was done, but the government, in the midst of the Chinese Civil War, halted work in 1947. The total capacity of those four dams is 38,500 MW,[148] almost double the capacity of the Three Gorges. In November 2007, it was reported in the local media that construction of the ship lift started in October 2007. TRENDING: Photo Appears to Show Black Lives Matter Supporters Holding Down and Kneeling on Neck of White Baby. [82] The wall beyond is to separate spillway and turbine flows from the lock and ship lift upstream approach channel. Trump Confidante Mike Lindell Points to Report that China, Russia and Others Interfered in 2020 Election, Capitol Police intelligence report before Jan. 6 riot warned 'Congress itself' could be targeted: report, Antifa Activist Daniel Alan Baker Arrested for Plotting to Murder Trump Supporters -- Tells Supporters on YouTube He Received Soros Money, Capitol Police intelligence report before Jan. 6 riot warned ‘Congress itself’ could be targeted: report, Antifa Activist Daniel Alan Baker Arrested for Plotting to Murder Trump Supporters — Tells Supporters on YouTube He Received Soros Money, Online Publications & Their Comment Sections, The Taverns of the Modern Era, Biden’s inaugural rehearsal postponed, security concerns cited. [28] In 1932, the Nationalist government, led by Chiang Kai-shek, began preliminary work on plans in the Three Gorges. [29] Some 54 Chinese engineers went to the U.S. for training. Maximum vessel size is 10,000 tons. [96] Other aquatic species have been endangered by the dam, particularly the baiji, or Chinese river dolphin,[85] now extinct. In July of 2018 a Korean-built dam collapsed on the border of Laos and Cambodia, killing what may have been hundreds … although reliable numbers are hard to come from the Lao government. The Three Gorges Dam didn’t have a separate body for quality inspection. 27, finished its final test, the six underground main generators are also in operation, raising capacity to 22.5 GW. These locks are staircase locks, whereby inner lock gate pairs serve as both the upper gate and lower gate. The ship locks are to the right (northeast) of the ship lift. From 2003 to 2007, power production equaled that of 84 million tonnes of standard coal.[83]. However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. Accordingly to numerous reports, the world's largest dam is in severe difficulty due to upstream flooding. (function(d, s, id) { [32][33] Construction started on December 14, 1994. Beijing has admitted in a rare revelation that ts 2.4-kilometer Three Gorges Dam spanning the Yangtze River in Hubei province “deformed slightly”, with some nonstructural, peripheral parts of the dam had buckled, after record flooding. CHINA is facing new cover-up claims amid fears the world’s biggest dam is about to collapse causing a tidal wave which could wipe out entire … [34] The dam was expected to be fully operational in 2009, but additional projects, such as the underground power plant with six additional generators, delayed full operation until May 2012. The Three Gorges Dam. In 1958, after the Hundred Flowers Campaign, some engineers who spoke out against the project were imprisoned. The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. Shortly before 1:30 this morning, the 13th federal inmate in the past, President Trump confidante Mike Lindell appears to be the only one left, Antifa supporter Daniel Alan Baker was arrested for plotting to murder Trump, Back in 1775 there used to be a place for daily political, Joe Biden’s inauguration rehearsal has been postponed due to security concerns. [94] These rare species are also used as ingredients in traditional Chinese medicines. Nuclear Power Plants in Danger? The flood covered Wuhan, a city of eight million people, for over three months, and the Jingguang Railway was out of service for more than 100 days. The ship lift takes 30 to 40 minutes to transit, as opposed to the three to four hours for stepping through the locks. Some newer ones are air-cooled, which are simpler in design and manufacture and are easier to maintain. – – FAILED DAMS UPSTREAM OF THREE GORGES DAM COLLAPSE- Very Good Analysis ; Behind the Three Gorges Dam [10] After nine years of construction, installation and testing, the power plant was fully operational by July 2012. Plenty of farm land and China's most important industrial area are built beside the river. [112][113] That is 30 m (98 ft) longer than those on the St Lawrence Seaway, but half as deep. On July 18, 2020, the Chinese state-run press agency Xinhua News Agency stated that "the monitoring records of the Three Gorges Project's operation department showed that the average values of the main parameters such as dam displacement, seepage, and deformation were within the normal range, and the safety indicators of the dam's water retaining structure were stable. According to a forecast, the inbound flow of water is expected to reach more than 74,000 cubic meters per second after continuous heavy rain battered the upper reaches of the Yangtze River. Each main water turbine has a capacity of 700 MW. The original plans called for the dam to employ a unique method for moving ships: the ships would enter locks located at the lower and upper ends of the dam and then cranes would move the ships from one lock to the next. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. [40], The government estimated that the Three Gorges Dam project would cost 180 billion yuan (US$22.5 billion). The ship lift's design uses a helical gear system, to climb or descend a toothed rack. China finally admits Its Three Gorges Dam has ‘deformed slightly’ but claims it happened over the weekend, ignoring reports this happened long ago. xfbml : true, // parse social plugins on this page [79], The dam was expected to provide 10% of China's power. [116] One complicating factor is that the water level can vary dramatically. After the 1949 Communist Revolution, Mao Zedong supported the project, but began the Gezhouba Dam project nearby first, and economic problems including the Great Leap Forward and the Cultural Revolution slowed progress. [5][6] The dam generates an average 95±20 TWh of electricity per year, depending on annual amount of precipitation in the river basin. [117] An article in Steel Construction says the actual time of the lift will be 21 minutes. [70] On June 30, 2009, after the river flow rate increased to over 24,000 m3/s, all 28 generators were switched on, producing only 16,100 MW because the head available during flood season is insufficient. [68][69] In July 2008 it generated 10.3 TWh of electricity, its first month over 10 TWh. [94] Freshwater fish are especially affected by dams due to changes in the water temperature and flow regime. The dam's reservoir rose nearly 3 m (9.8 ft) in 24 hours and reduced the outflow to 40,000 m3/s (1,400,000 cu ft/s) in discharges downstream, effectively alleviating serious impacts on the middle and lower river. The smaller dam’s failure had not been reported by local media, raising questions of what the Chinese government could be hiding about the Three Gorges. [72], During the November to May dry season, power output is limited by the river's flow rate, as seen in the diagrams on the right. The moving mass (including counterweights) is 34,000 tonnes. In 2012, the dam's 32 generating units generated a record 98.1 TWh of electricity, which accounts for 14% of China's total hydro generation. Learn more about the Three Gorges Dam. A major concern, after several weeks of raging floodwaters rushing through the dam at 60,000 cubic meters … In 1944, the United States Bureau of Reclamation's head design engineer, John L. Savage, surveyed the area and drew up a dam proposal for the 'Yangtze River Project'. [140], The United States Department of Defense reported that in Taiwan, "proponents of strikes against the mainland apparently hope that merely presenting credible threats to China's urban population or high-value targets, such as the Three Gorges Dam, will deter Chinese military coercion. Other provinces had to pay an additional charge of ¥4.00 per MWh. The "arriving silt—so long as it does arrive—strengthens the bed on which Shanghai is built... the less the tonnage of arriving sediment the more vulnerable is this biggest of Chinese cities to inundation...", This page was last edited on 15 January 2021, at 04:41. Construction was completed in December 2007, one year ahead of schedule. When the water level is at its maximum of 175 m (574 ft) above sea level, 110 m (361 ft) higher than the river level downstream, the dam reservoir is on average about 660 km (410 mi) in length and 1.12 km (3,675 ft) in width. [12][13] Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW. The ship lift is to the right of the dam body with its own designated waterway. Before the dam was constructed, the maximum freight capacity at the Three Gorges site was 18.0 million tonnes per year. [44], Power generation is managed by China Yangtze Power, a listed subsidiary of China Three Gorges Corporation (CTGC)—a Central Enterprise SOE administered by SASAC. All other rights are reserved for The Spectator Media, unless otherwise noted. For example, the hanging coffins site high in the Shen Nong Gorge is part of the cliffs. The maximum power-output curves were calculated based on the average flow rate at the dam site, assuming the water level is 175 m and the plant gross efficiency is 90.15%. [132] About 140,000 residents were relocated to other provinces. Shanghai, more than 1,600 km (990 mi) away, rests on a massive sedimentary plain. The total capacity of the ship locks is expected to reach 100 million tonnes per year.[83]. By providing flood storage space, the dam reduces the potential for floods downstream which could possibly affect millions. [27][28] He stated that a dam capable of generating 30 million horsepower (22 GW) was possible downstream of the Three Gorges. [118][119] Three Gorges Dam collapse. Many other fish are injured in the turbine blades of the hydroelectric plants as well. [111] The locks are 280 m long, 35 m wide, and 5 m deep (918 × 114 × 16.4 ft). The report said the towers had reached 189 m (620 ft) of the anticipated 195 m (640 ft), the towers would be completed by June 2012 and the entire shiplift in 2015. In addition to the canal locks, there is a ship lift, a kind of elevator for vessels. “With hindsight, I think that all those experts who opposed the buildings of the Three Gorges were right,” Zhang said on Radio Free Asia. The water also powers the Gezhouba Dam downstream. But not just to China. 15 started up on October 30, 2008.

The deformation occurred last Saturday when the flood from western provinces including Sichuan and Chongqing along the upper reaches of the Yangtze River peaked at a record-setting 61,000 cubic meters per second, according to China Three Gorges Corporation, a state-owned enterprise that manages the dam and the sprawling power plant underneath it. However, electricity demand has increased more quickly than previously projected. The outer diameter of the generator stator is 21.4/20.9 m. The inner diameter is 18.5/18.8 m. The stator, the biggest of its kind, is 3.1/3 m in height. [13] The sixth (No. [126], In late 2012, preliminary work started along both future railway routes. [128] As of June 2008, China relocated 1.24 million residents (ending with Gaoyang in Hubei Province) as 13 cities, 140 towns and 1350 villages either flooded or were partially flooded by the reservoir,[129][130][131] about 1.5% of the province's 60.3 million and Chongqing Municipality's 31.44 million population. According to the Ministry of Environmental Protection, as of April 2007, more than 50 new plants could treat 1.84 million tonnes per day, 65% of the total need. In 1998, a flood in the same area caused billions of dollars in damage; 2,039 km2 (787 sq mi) of farmland were flooded. The largest dam in the world, it allows the navigation of oceangoing freighters, generates hydroelectric power, and may offer flood protection. [98] The dam contributed to the functional extinction of the baiji Yangtze river dolphin. [104] Also, the dam cannot protect against some of the large tributaries downstream, including the Xiang, Zishui, Yuanshui, Lishui, Hanshui, and the Gan. [90], The dam catalyzed improved upstream wastewater treatment around Chongqing and its suburban areas. JOIN OVER 35,000+ PATRIOTS IN RECEIVING REAL, ACCURATE, AND AMERICAN-CENTRIC NEWS! Posted by AURaptor on 7/27/20 at 6:23 pm to Bengalbio There is massive flooding, and some destruction, and staggering crop losses, but there has been some misinformation as well. The Tibet Autonomous Region pays no surcharge. It contains 39.3 km3 (31,900,000 acre⋅ft) of water and has a total surface area of 1,045 km2 (403 sq mi). Besides, Mr. Wang pointed out that the design, construction and quality assessment of the dam were all done by the same expert teams and the project completion time was too fast. [139] Cultural and historical relics are being moved to higher ground as they are discovered, but the flooding inevitably covered undiscovered relics. The DC transmission line HVDC Three Gorges – Guangdong to the South China Grid has a capacity of 3,000 MW. version : "" re: Is the Three Gorges Dam About to Collapse? In a rare revelation, Beijing has admitted that its 2.4-kilometer Three Gorges Dam spanning the Yangtze River in Hubei province “ deformed slightly ” after record flooding. Torrential rains have been causing havoc throughout the southwest and central region this month, with many rivers bursting their banks, prompting mass evacuations. As there are separate sets of locks for upstream and downstream traffic, this system is more water efficient than bi-directional staircase locks. Since then, the price has varied by province, from ¥228.7–401.8 per MWh. [123] It says that the expected dimensions of the 3,000 tonnes (3,000,000 kg) passenger vessels the ship lift's basin was designed to carry will be 84.5 by 17.2 by 2.65 metres (277.2 ft × 56.4 ft × 8.7 ft). The water level upstream drops from 175 to 145 m (574 to 476 ft),[107] preparing for the rainy season. People have even created simulations of the dam collapsing and one recent video went viral on social media. [19] However, the dam flooded archaeological and cultural sites, displaced some 1.3 million people, and had caused significant ecological changes including an increased risk of landslides. appId : "", Pollution. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. Additional charges were assessed as follows: Every province receiving power from the Three Gorges Dam had to pay ¥7.00 per MWh extra. But the integrity of the Three Gorges Dam remains under fire, as officials say despite draining efforts, constant rain may still see it collapse. On a more serious … Higher-paying customers, such as Shanghai, receive priority. Though it was close to this level even at the start of construction, the dam further decreased its habitat and increased ship travel, which are among the factors causing what will be its ultimate demise. The dam is expected to minimize the effect of even a "super" flood. [85] Because the flow is slower above the dam, much of this sediment will now settle there instead of flowing downstream, and there will be less sediment downstream. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. ", In order to maximize the utility of the Three Gorges Dam and cut down on sedimentation from the Jinsha River, the upper course of the Yangtze River, authorities plan to build a series of dams on the Jinsha, including Wudongde Dam, Baihetan Dam, along with the now completed Xiluodu and Xiangjiaba dams. [99], In 2005, NASA scientists calculated that the shift of water mass stored by the dams would increase the total length of the Earth's day by 0.06 microseconds and make the Earth slightly more round in the middle and flat on the poles.[100]. Three Gorges Dam secretly discharged, internal doc reveals; China firm used fake gold to obtain loan ; Three Gorges Dam releasing floodwater from spillway deliberately? [43], Funding sources include the Three Gorges Dam Construction Fund, profits from the Gezhouba Dam, loans from the China Development Bank, loans from domestic and foreign commercial banks, corporate bonds, and revenue from both before and after the dam is fully operational. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. The electricity generated is then stepped-up to 500 kV for transmission at 50 Hz. It is home to 6,388 species of plants, which belong to 238 families and 1,508 genera. However, the municipal government explained that the relocation is due to urbanization, rather than the dam, and people involved included other areas of the municipality. [134][135][136] Despite protests by residents and environmentalists, the Three Gorges Dam was completed in 2006 after a 12-year build. // initializing facebook 9. [41] By the end of 2008, spending had reached 148.365 billion yuan, among which 64.613 billion yuan was spent on construction, 68.557 billion yuan on relocating affected residents, and 15.195 billion yuan on financing. [76] Nine provinces and two cities consume power from the dam. Flooding in the area is much worse than ever before and… “Since it was built, it has never played a role in preventing flooding or droughts, like we thought it would back then.”. window.fbAsyncInit = function() { [39] The concrete dam wall is 181 m (594 ft) high above the rock basis. China's controversial Three Gorges Dam, the world's biggest hydropower project, is structurally sound, officials said, denying rumours on social media it was at risk of collapse. As a result, damage to an individual section should not affect other parts of the dam. [84] One is that sedimentation projections are not agreed upon, and the other is that the dam sits on a seismic fault. The generator produces electrical power at 20 kV. Please update this article to reflect recent events or newly available information. [80][81], According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. In fact, Chinese Government scholars even claim that the Three Gorges Dam directly caused the extinction of the baiji. The National People's Congress approved the dam in 1992: out of 2,633 delegates, 1,767 voted in favour, 177 voted against, 664 abstained, and 25 members did not vote, giving the legislation an unusually low 67.75% approval rate. The designed hydraulic head of the generator is 80.6 meters (264 ft). js = d.createElement(s); js.id = id; Two hazards are uniquely identified with the dam. This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. The alternating current (AC) lines to the Central China Grid have a total capacity of 12,000 MW. if (d.getElementById(id)) return; In a rare revelation, Beijing has admitted that its 2.4-kilometer Three Gorges Dam spanning the Yangtze River in Hubei province “deformed slightly” after record flooding. In 2018, the dam generated 101.6 terawatt-hours (TWh), breaking its previous record, but was still slightly lower than the Itaipú Dam, which had set the world record in 2016 after producing 103.1 TWh. [16][114] The vertical distance traveled is 113 m (371 ft),[115] and the size of the ship lift's basin is 120 m × 18 m × 3.5 m (394 ft × 59 ft × 11 ft). It is not known whether this solution was considered for its water-saving performance or because the engineers thought the difference in height between the river above and below the dam too great for alternative methods. Three Gorges Dam, dam on the Yangtze River (Chang Jiang) just west of the city of Yichang in China. Of the 3,000 to 4,000 remaining critically endangered Siberian crane, a large number currently spend the winter in wetlands that will be destroyed by the Three Gorges Dam. The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges.
