摘　　要：王甫洲水利枢纽围堤局部堤段下游排水沟产生渗透变形,对围堤的稳定构成威胁。通过分析排水沟变形坍塌的成因,提出在水库正常运行、不降低库水位的情况下,通过修改排水沟结构的设计,采用井点降水、铺垫压坡等施工技术,确保排水沟修复施工质量。获得了满意的修复效果。Parts of the downstream drainage ditch in Wangfuzhou Hydro Project embankment taken place seepage deformation and the stability of embankment was threatened.By analyzing the causes of collapse,the rehabilitation was conducted under the conditions of normal operation level,in which,the ditch structure was redesigned,and the construction technologies of well point dewatering and slope sandbags reinforcement were used.The repair is satisfactory.
