摘　　要：某电站尾水渠边坡在暴雨及洪水冲刷过后局部发生较大变形,在水下施工对其进行加固难度较大,首先采用水下摄像及量测查明变形幅度,然后结合数值模拟计算,对边坡变形原因进行了分析研究,根据分析结果和方案比选,采取了水下封堵灌浆、锚筋桩及排水等综合措施加固边坡。加固施工不影响电站运行,取得了较好的效果,可为类似工程提供参考。After the heavy rain and flood,the slope of the power station tailrace has a large sliding deformation,and it is difficult to reinforce it under water.According to the result of underwater detection and numerical value simulation,the reason of slope sliding is analyzed and studied.Based on the results of the analysis and plan comparison,using the comprehensive reinforcement measures of underwater grouting and the anchor bolt and drainage to reinforce the slop.The reinforcement construction did not affect the operation of the power station and achieved good results.This method can be a reference for similar projects.
