What is the Three Gorges Dam famous for?
It's the world’s largest hydropower project and it's famous for the beautiful scenery.
三峡袭大坝百是世界上最大的度水电站,也以景问色优美而著称。答
The Three Gorges Dam (Chinese: 长江三峡大坝) is a hydroelectric river dam that spans the Yangtze River in the town of Sandouping, located in the Yiling District of Yichang, in Hubei province, China. It is the world's largest electricity-generating plant of any kind.The dam body was completed in 2006. Except for a ship lift, all of the originally planned components of the project were completed on October 30, 2008 when the 26th generator was brought into commercial operation. Currently, it contains 26 completed generators in the shore power plant, each with a capacity of 700 MW. Six additional generators in the underground power plant are being installed and are not expected to become fully operational until around 2011. Coupling the dam's 32 main generators with 2 smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW. The project produces hydroelectricity, increases the river's navigation capacity, and reduces the potential for floods downstream by providing flood storage space. From completion until September 2009 the dam has generated 348.4 TWh of electricity, covering more than one third of its project cost.The project management and the Chinese state regard the project as an historic engineering, social and economic success, with the design of state of the art large turbines, and a move toward the reduction of greenhouse gas emissions. However, the dam has also flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The building of the dam has been a controversial topic both in China and abroad.希望帮到你啦~636f7079e799bee5baa6e79fa5e98193331
The Three Gorges Dam project is one of the most controversial international river issues. The dam would cross the Yangtze River, which is a the third largest river in the world, at a point where the river is a mile wide. The 610 foot dam would create a 39 billion cubic meter reservoir that would stretch for 400 miles. 3 Not only is this the largest dam ever built, it is the largest construction undertaking. Financial backing has come from many national and international sources, including United States companies. China has also sought outside engineering and construction consulting from companies including Caterpillar Construction Company.
A dam on the Yangtze River was first proposed by Sun Yatsen in 1919 for power generation purposes. This prosoal never came about because of economic and political strife. Many leaders dreamed of taming the Yangtze River. Life along the Yangtze River can be treacherous because of the deadly flooding known to devastate cities and lives.
The Three Gorges Dam is located in Sandouping Town, Yichang City, Hubei Province, China. It is 38 kilometers from the Gezhouba Hydropower Project downstream.
It is the main project of the Three Gorges Hydropower Station, the core landscape of the Three Gorges Dam tourist area and the eastern end of the Three Gorges Reservoir.
The Three Gorges Dam project consists of two parts, the main building and diversion project, with a total length of about 3335m and a crest elevation of 185 meters. The total investment of the project is 95.460 billion RMB.
Construction was officially started on December 14, 1994 and the whole line was successfully constructed on May 20, 2006.
三峡大坝,位于中国湖北省宜昌市三斗坪镇境内,距下游葛洲坝水利枢纽工程38公里,是当今世界最大的水利发电工程——三峡水电站的主体工程、三峡大坝旅游区的核心景观、三峡水库的东端。e799bee5baa6e997aee7ad94e4b893e5b19e366
三峡大坝工程包括主体建筑物及导流工程两部分,全长约3335m,坝顶高程185米,工程总投资为954.6亿人民币,于1994年12月14日正式动工修建,2006年5月20日全线修建成功。
扩展资料
三峡大坝主要好处:
1、发电:
三峡巨大的流量和落差,使得三峡大坝的发电量居世界第一,就光是发电创造的价值也是惊人的,水力发电对环境的污染比起传统的发电模式要小太多。
2、航运:
三峡大坝对于周围落后库区的交通是有利的,三峡大坝建成后水位升高,淹没部分险滩等。拓宽了航道,万吨级的船队由此可直达江海,形成了一条长江黄金水道,对长江沿线和出口沿海地区来说都是发展的好机会。
3、防洪:
三峡大坝可以非常有效的控制洪水,98年的洪水大家都还记忆犹新,每到雨季,三峡片区雨量大,并且分布不均匀,极容易部分地区发大洪水。而三峡大坝巨大的可调节容量有效的缓解了下游的压力,控制了洪水,保证了大量的财产和人身安全。
4、其他:
三峡大坝对我国“南水北调”工程、水产养殖业、改善区域气候等等也有很大的益处。
