举世瞩目的长江三峡水利枢纽工程,位于湖北省宜昌县三斗坪镇,距下游已建成的葛洲坝水利枢纽38公里。三峡大坝正常蓄水位175m,防洪限制水位145m,枯季消落低水位155m,初期按蓄水位156m,防洪限制水位135m 运行。大坝控制流域面积100万平方公里,年平均迳流量4510亿立方米,是一座具有防洪、发电、航运和供水、旅游等巨大综合效益的特大型水利枢纽工程。其工程量是葛洲坝的2.5倍,是世界目前最大的水利枢纽——巴西伊泰普水电站的1.2倍。工程将采用“一级开发,一次建成,分期蓄水,连续移民”的建设方案。枢纽主要建筑物枢纽工程主体建筑由拦河大坝、水电站、通航建筑三大部分组成:拦河大坝坝顶高程
The Three Gorges Project, which has attracted worldwide attention, is located in Sandouping Town, Yichang County, Hubei Province, 38 kilometers away from the completed Gezhouba Dam. The Three Gorges Dam has a normal water storage level of 175m and a flood control restricted water level of 145m. During the dry season, the water level fluctuates at a low level of 155m. In the initial stage, it operates at a water storage level of 156m and a flood control restricted water level of 135m. Dam control basin area of 1 million square kilometers, the average annual flow of 451 billion cubic meters, is a flood control, power generation, shipping and water supply, tourism and other large-scale integrated benefits of large-scale water control project. The project volume is 2.5 times that of the Gezhouba Dam, which is 1.2 times of that of the Itaipu Hydropower Station, the largest hydropower station in the world. The project will adopt the construction plan of “one-level development, one-time construction, phased water storage and continuous resettlement”. The main building of the hub The main project of the Hub Project is composed of three parts: dam, hydropower station and navigation and navigation dam.
