摘　　要：横泉水库大坝坝体与上游护坡、下游排水棱体之间以及防渗墙下游至排水棱体处坝基处设有反滤。坝基防渗采用塑性混凝土防渗墙与帷幕灌浆结合方案。本次地勘对坝体钻孔及挖探坑取样试验,根据取样试验参数采用软件计算渗流稳定,通过计算结合现有监测数据分析判断坝体稳定。The dam foundation of Hengquan Reservoir is equipped with inverted filter between the dam body and upstream slope protection,between the dam body and the downstream drainage prism and from the downstream of cutoff wall to the drainage prism.The combination scheme of plastic concrete cutoff wall and curtain grouting is adopted for dam foundation seepage control.In this geological exploration,the sampling test of drilling and digging test pits of the dam body are carried out.According to the dam soil sampling test parameters,the seepage stability is calculated by software,and the dam stability is judged by calculation and the monitoring data analysis.
