摘　　要：2016年汛期清江梯级水电站同时开闸泄洪,汛后对高坝洲大坝消力池、隔河岩大坝消力池、隔河岩一级升船机上闸首门槽、晒谷坪电站进水口、水布垭大坝R4-R5面板、水布垭电站进水口等处进行了水下检查,发现了隔河岩大坝消力池底板有大面积冲磨,对高坝洲大坝消力池、水布垭电站进水口拦污栅淤积物进行了清理,消除了电站运行安全隐患,对冲磨较严重的部位将择时进行修复。In the flood season of 2016, the cascade hydropower stations in Qingjiang River discharged flood water in the same time. After the flood, underwater inspections are carried out on the energy dissipation and scouring prevention are- as and some other hydraulic structures in the cascade stations, including the stilling basins of Gaobazhou and Geheyan Hydropower Stations, the upper gate groove in Geheyan Shiplift, the water inlets in Shaiguping and Shuibuya Hydropow- er Stations, and the R4 - R5 concrete face of Shuibuya Dam. A large scouring area is observed in the stilling basin base- board in Geheyan Hydropower Station, which will be repaired in time. Also, sediments in the stilling basin of Gaoba- zhou Hydropower Station and the trash rack in the inlet of Shuibuya Hydropower Station are cleared. Thus, the operation safety risks of these stations are successfully eliminated.
