本文针对沙湾水电站投入运行后泄洪冲沙闸坝下防冲槽内防冲砼块下沉、移位，周边河床淘刷形成冲坑问题，进行了探讨和原因分析。由于电站进入运行期，泄洪冲沙闸随时可能泄放水，相对施工期施工难度大，本文介绍了导流排水、临时围堰残梗拆除、冲坑回填实施方案。

This paper aiming at problems that scour prevent-ion concrete block is sinking, shift in anti-scour trench under water flushing sites after Shawan hydropower station put into operation, framing the scouring pit around the river by under-mining, makes the discussion and reason analysis. Because the power station into operation period, release flood waters sedi-ment flushing sluice may release at any time, it is relatively di-fficult than construction period, this paper introduces the diver-sion drainage, temporary cofferdam demolition, stubble scour pit backfil scheme.
