摘　　要：水泥灌浆使基岩与坝体连成一体,将岩体内的节理裂隙充填胶结,形成设想的实际不透水的防渗帷幕。群孔压水试验就是利用一个钻孔做压水试验,观测其它观测孔水位变化,确定岩体的透水性和水力联系情况的一种试验。文章结合松山大坝趾板帷幕工程,详细介绍了群孔压水试验在防渗检测中的应用情况,及所取得的成果。The bedrock and dam body are connected by the cement grouting,then the joint fissure of rock body are filled and cemented,which forms the actual impermeable anti-seepage curtain.Group holes water pressure test is doing water pressure test in a drill hole meanwhile observesing water level change of other drills,and then determining permeability and hydraulic connection of rock.Based on toe slab curtain project of Songshan dam,the paper introduces application of group holes water pressure test in anti-seepage detection in detail,and the results achieved.
