横卧在长江上的三峡大坝已经达到挡水所要求的坝高。根据三峡工程建设计划，三峡大坝上游基坑迎水面将从4月25日开始充水，1997年大江截流形成的上游围堰将于5月1日破堰进水。 三峡大坝是混凝土重力坝，大坝全长2 309 m，坝顶海拔高程185 m，最大坝高181 m，整个大坝混凝土浇筑
The Three Gorges Dam, lying on the Yangtze River, has reached the dam height required for retaining water. According to the construction plan of the Three Gorges Project, the water level of the foundation pit on the upper reaches of the Three Gorges Dam will be filled with water from April 25, and the upstream cofferdam formed by the river closure in 1997 will start to inflate the weir on May 1. The Three Gorges Dam is a concrete gravity dam with a total length of 2 309 m. The crest elevation is 185 m and the maximum dam height is 181 m. The entire dam concrete placement
