三峡工程是一项具有防洪、发电、航运等综合效益的大型水利机纽工程。坝址位于湖北省宜昌市三斗坪镇,大坝全长1983m,坝顶高程185m,水库正常蓄水位175m,总库容3.93×10~(10)m~3,总装机容量1.768×10~7kW。所需静态投资按1990年价格为570亿元,工期18年。 三峡工程不仅规模大,投资多,建设周期长,技术复杂,而且移民而广量大。 据1985年统计,按正常蓄水位175m的建设方案,水库将淹没涉及川、鄂二省19个县(市)的140个集镇、326个乡,淹没区人口72.55万人,其中城镇人口39.29万人,农村人口33.26万人,淹没耕地238km~2。考虑到20
The Three Gorges Project is a new large-scale water conservancy project with comprehensive benefits such as flood prevention, power generation and shipping. The dam site is located in Sandouping Town, Yichang City, Hubei Province. The dam has a total length of 1983m, and the crest elevation is 185m. The normal water storage level of the reservoir is 175m, the total storage capacity is 3.93x10~(10)m~3, and the total installed capacity is 1.768×10~ 7kW. The static investment required was 57 billion yuan in 1990, and the duration was 18 years. The Three Gorges Project is not only large-scale, has many investments, has a long construction period, is complicated in technology, and has a large amount of immigration. According to statistics from 1985, according to the construction plan for a normal water level of 175m, the reservoir will inundate 140 market towns and 326 townships in 19 counties (cities) in Sichuan and Hubei Provinces. The population of the inundation area is 725,500, of which the urban population is 39.29. Million people, the rural population of 33.26 million, submerged arable land 238km~2. Considering 20
