三峡大坝的建筑格局
三峡大坝按千年一遇洪水流量9.88万立方米每秒设计，相应的挡水位为175米；校核按万年一遇洪水加大10%洪水流量12.43万立方米每秒设计，相应的挡水位为180.4米。泄洪坝段布置在河床中部，泄洪设施为深孔和表孔。
泄洪坝段前缘总长483米，分为23个坝段，每个坝段中部设宽7米、高9米的泄洪深孔，进口底高程90.0米；2个坝段之间跨缝布置净宽8米的泄洪表孔，溢流堰顶高程158米。
为满足施工导流及截流要求，在表孔的正下方跨缝布置22个导流底孔，出口宽6.0米、高8.5米，中间的16个孔进口底高程为56米，两侧各3个孔的进口底高程为57米。
英语作文三峡大坝的好处和坏处（短句）
As with many dams, there is a debate over costs and benefits. Although there are economic benefits such as flood control, clean hydroelectricity and navigation, there are also concerns about the relocation of people, siltation, loss of archaeological and cultural sites and the impact on regional ecosystem
While the country benefits from gargantuan potential of electricity generation, we have to face up to various environmental conservation issues concerning geological and ecological environment along both river sides and whole upper reaches. The professional designers of the great dam now have to work out a practical way to prevent and remedy pollution effectively, which has already been the focus of world attention.
三峡大坝的地理位置、功能,特点，用英文说
The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world's largest power station in terms of installed capacity (22,500 MW). In 2014 the dam generated 98.8 TWh of electricity, setting a new world record by 0.17 TWh previously held by the Itaipú Dam on the Brazil/Paraguay border in 2013 of 98.63.[4][5][6] But in 2015, the Itaipu power plant resumed the lead in annual worldwide production, producing 89.5 TWh, while production of Three Gorges was 87 TWh.[7][8][9]
Except for a ship lift, 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. The ship lift was complete in December 2015.[12] Each main water turbine has a capacity of 700 MW.[13][14] The dam body was completed in 2006. 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.[13][15][16]
As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity and reduce the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success,[17] with the design of state-of-the-art large turbines,[18] and a move toward limiting greenhouse gas emissions.[19] However, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides.[20] The dam has been a controversial topic both domestically and abroad.[21]

简介三峡大坝的英语短文
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~
