摘　　要：为了有效地解决在承压水区破碎岩体施工帷幕灌浆时出现孔口冒浆和灌浆压力过小的问题。从灌浆压力、浆液配比、灌浆方式等方面进行现场试验,结合现场试验情况,提出稳定浆液和双套管结合的方案,完成承压水区帷幕灌浆防渗并达到设计要求,可为类似工程提供借鉴。In order to effectively solve the problem that the grout and grouting pressure are too small in the grouting of the fractured rock mass in the confined water area,from the ratio of grouting pressure,grout and grouting methods field test is conducted.Combined with field test,the stable grout and dual combined casing program are put forward,which successfully completes the confined water curtain grouting anti-seepage task and meets the design requirements,and can provide reference for similar projects.
