葛洲壩水利樞紐工程

The experimental dam of the TGP(Three Gorges Project) Gezhouba Water Control Project is located at the lower end of the Three Gorges in the suburb of Yichang City, 2.3 km near Nanjin pass of Xiling Gorge, 38 km downstream of the TGP.

葛洲壩水利樞紐工程是長江第一座水利樞紐工程，是三峽工程的實驗壩，位於長江三峽出口，湖北省宜昌市區，距離西陵峽口南津關2.3千米，距上游的三峽大壩38千米。

The Dam is 2595 meters long, with a total storage capacity of l.58 billion m3 and a maximum flood discharging capability of 110,000 m3/s. The two hydro-electric plants have 21 generating units with a total installed capacity of 2.715 million kw. and annual output of 15.7 billion kwh. The annual one-way shipping capacity of the navigation facilities is 50 million tons.

大壩全長2595米，總庫容量15.8億立方米，最大泄洪量，爲每秒11萬立方米。水電站共兩座，一在大江，裝機14臺；一在二江，裝機7臺，總容量271.5萬千瓦。採用低水頭徑流發電，年均發電可達157億度。三座船閘年單向通過能力爲5000萬噸。

The construction of the Gezhouba Project, including two stages, started in 1970. On January 3, 1981, the Yangtze River was completely blocked and the construction of the second stage of the project begun. The whole project ended in 1991.

葛洲壩水利樞紐工程於1970年動工，分兩期進行建設。1981年1月3日大江截流，6月二、三江蓄水通航發電，一期工程基本完成。第二期大江工程於1982年開始施工，1986年大江電站第一臺機組開始發電，1988年14臺機組全部建成併網發電。1991年整個樞紐工程全部竣工。
