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.
