摘　　要：乌江渡水电站泄洪建筑物的消能防冲是电站安全运行的问题之一．通过对尾水河道冲刷监测资料的分析研究，表明尾水河床冲刷坑的深度已趋稳定．且远离厂坝，不会危及厂坝基础安全，其消能防冲措施是比较成功的。但泄洪对岸坡的冲淘也是比较严重的。Energy dissipation of discharge system in Wujiangdu hydropower station is a key issue of safty operation for the plant. By the analysis of scouring monitoring data on the tailrace riverbed, the results show the washout depth of tailrace riverbed becoming stable,far away from the dam, no risk for the dam aam Powerhouse. The conclusion in that the measures of energy dissipation and anti-scouring are successful.
