摘　　要：如何解决低水头径流式电站的防沙问题,防止发电进水口淤积,减少泥沙过机一直是水工建筑物检修的技术难点,通过对葛洲坝大江电厂排沙底孔上游检修门槽底坎区域冲坑成因的分析及处理方法的研究,希望能够对同类型水工建筑物检修提供借鉴。It＇s a technical and difficult problem on the maintenance of hydraulic structures about how to deal with sediment discharge, decrease sediment accumulation before dam and an amount of sand flowing through hydraulic turbine for low head run - off - river power stations. By genetic analysis and treatment of scouring pits in the area of service gate slot for sediment bottom sluice of Gezhouba First power plant, which can provide useful reference for similar projects.
