摘　　要：针对某隧道施工中遇到的局部渗水和富水层涌水问题,通过地质勘察与水文分析、技术方案设计与实施以及实地监测渗水涌水情况,提出并验证了全断面超前帷幕注浆加固技术的效果与应用价值。验证结果发现,全断面超前帷幕注浆加固技术能够有效形成连续、致密的注浆帷幕,显著降低地下水渗透系数,有效阻断地下水渗出和涌出,为隧道开挖创造了良好的作业条件。In response to the problems of local water seepage and water-rich layer water gushing encountered dur-ing the construction of a certain tunnel,the effectiveness and application value of the full-section advanced curtain grouting reinforcement technology are proposed and verified through geological exploration and hydrological analy-sis,technical scheme design and implementation,and on-site monitoring of water seepage and gushing.The results show that the full section advanced curtain grouting reinforcement technology can effectively form a continuous and dense grout curtain,significantly reduce the groundwater permeability coefficient,effectively block groundwa-ter seepage and gushing,and create a good working condition for tunnel excavation.
