作为世界上发电能力最大的水利工程,1992年4月3日,三峡工程正式开工。1997年11月,大江首次截流,长江水位提高了10米,江水沿修建在中堡岛的导流明渠下泄,三峡景观基本不受影响。2002年底至2003年6月,在导流明渠截流后,大坝将逐步蓄水,长江三峡水位将由目前的66米提高到135米。2006年9月,大坝再次提高到150米,水面及长江三峡景点变化不大。2009年,工程全面完工,经过20至30年的运行,其蓄水水位最终达到175米,坝前水位将提高近110米左右。
As the world’s largest power generation capacity of water conservancy projects, April 3, 1992, the Three Gorges Project officially started. In November 1997, the river was cut off for the first time and the water level of the Yangtze River was raised by 10 meters. The river drained along the diversion channel constructed at Fort Island, and the landscape of the Three Gorges was basically unaffected. From the end of 2002 to June 2003, after the closure of the diversion channel, the dam will gradually accumulate water and the water level of the Three Gorges of the Yangtze River will be raised from the current 66 meters to 135 meters. In September 2006, the dam was again raised to 150 meters with little change in the water and the Three Gorges spots in the Yangtze River. In 2009, the project was fully completed. After 20 to 30 years of operation, its water level finally reached 175 meters, and the water level in front of the dam would increase by nearly 110 meters.
