五、最大的水利枢纽——葛州坝水利枢纽葛州坝水利枢纽位于长江三峡出口南津关下游约三公里的宜昌市境内,距市中心约六公里。枢纽布置主要由拦河坝、河床式厂房、船闸、泄洪闸、冲砂闸等建筑物组成。大坝全长2595米.最大坝高47米;控制流域面积100万平方公里,总库容为15.8亿立方米;水电站一座在大江,另一座在二江,装机21台,容量为271.5万千瓦;船闸有三座,其中二号船闸,闸室宽34米,长280米,能通万吨客轮、货轮和大型船队,是目前世界上最大的船闸之一。三座船闸年单向通过能力,近期为2000万吨,远期为5000万吨。葛州坝水利枢纽工程是将来的“三峡工程”的配套建筑,对三峡高坝起反调节作用。也是我国在万里长江上兴建的第一座大坝。
V. The Largest Water Control Project - Gezhouba Water Control Project Gezhouba Water Control Project is located in Yichang City, about three kilometers downstream from the Nanjin-Guan exit of the Three Gorges of the Yangtze River and about six kilometers from the city center. Hub layout mainly by the barrage, riverbed plant, ship lock, flood gate, red sand brake and other buildings. The total length of the dam is 2595 meters, the maximum dam height is 47 meters, the control basin covers an area of 1 million square kilometers and the total storage capacity is 1.58 billion cubic meters. One hydropower station is in the Dajiang River and the other is in the second river with 21 sets of capacity of 2.751 million kilowatts. There are three locks, of which two locks, lock chamber 34 meters wide and 280 meters long, can pass million tons of passenger ships, freighters and large fleets, is currently the world’s largest one of the locks. One-way capacity of three locks in the past, the recent 20 million tons, the long-term 50 million tons. Gezhouba dam project is the future “Three Gorges Project” ancillary buildings, the Three Gorges dam play an anti-regulatory role. It is also the first dam built on the Yangtze River in our country.
