摘　　要：在某隧洞施工过程中,由于岩石节理裂隙发育,洞内出现较大渗水和涌水。针对隧洞内的集中涌水、线状渗水和层间承压渗水,采用了合理的抽排水方式,实现了洞内渗水快速抽排的目的,增强了掌子面岩体的稳定性,提高了工作效率,取得了良好的效果。In the process to excavate a certain tunnel,due to the development of the rock joints and fissures,larger amounts of the seeping and gushing water occurred in the tunnel.Being aimed at concentratively gushing water,lineally seeping water and seeping confined water from the interlayer,the reasonable pump drainage way was taken,therefore the rapid pumping exhaust of seepage water was realized;the stability of rock mass on heading face was enhanced;the work efficiency was improved;the good results were achieved.
