摘　　要：清江水布垭水电站为世界最高面板堆石坝,其溢洪道采用千年一遇洪水标准设计、万年一遇洪水标准校核。溢洪道的体形轮廓与设计的相符性关系到泄洪流速、流态的变化,如果形体偏差过大,有可能产生空蚀,影响电站的安全和正常运行。本文介绍了水布垭水电站溢洪道主要轮廓尺寸的复测情况,并进行了施工偏差分析和评价。研究结果表明,水布垭水电站溢洪道的施工体形偏差较小,符合设计要求,不会对水电站的正常运行产生影响。The Shuibuya Dam in Qingjiang River is the world’s highest concrete faced rockfill dam.Its spillway was designed and verified based on the 1000-year flood standard.The consistency of the shape of the spillway with the design is related to the relationship between flood flow velocity and flow pattern changes.If the shape deviation is too large,there may be cavitation,affecting the safe and normal operation of the hydropower.This paper introduced the re-measurement of the main dimensions of the Shuibuya Dam spillway and evaluated the construction deviation.The results show that the construction deviation of the Shuibuya Dam spillway is relatively small,meeting the design requirements,and it will not affect the normal operation of the hydropower station.
