摘　　要：通过参窝水库等工程实践，介绍一种在水库正常运行情况下，进行横缝堵漏的方法———膨胀浆塞法，即在坝顶于大坝２道止水带之间骑横缝垂直造孔，用一次灌浆法，将水溶性聚氨酯复合料灌注入孔内，达到胀紧横缝止漏的目的。该法工艺简单，效果明显，工程造价低，止漏全面彻底。By experience in Canwo reservior,the paper introduces expanding slurry plugging up method,i.e.a way of stopping leakage in dam transverse joints while the reservior is working normally.First,make holes on both sides of transverse joints which are between two water stops and then pour water soluble polyurethane composite material into the holes with one grouting method.Thus transverse joints can be closed up due to expansion of the material inside the holes,i.e.leakage stopped.The method is simple,efficient and lowcost.[
