摘　　要：本文以引绰济辽工程为研究对象,针对引绰济辽工程输水工程隧洞段施工二标TBM掘进施工过程中出现的围岩碎裂、断层、风化蚀变强烈及滴水等工程地质问题,采取地表注浆加固、隧洞内加强支护综合处理措施,处理后效果良好,证明此方案切实可行,可以为同类型施工提供有益参考和借鉴。In response to the engineering geological problems such as rock fragmentation,faults,strong weathering and erosion,and dripping during the TBM excavation process of the second section of the water conveyance project of the Yinchuo Jiliao Project,comprehensive measures were taken to reinforce the surface grouting and strengthen the support inside the tunnel.The treatment effect was good,proving the feasibility of the plan,proving that this plan is feasible and can provide useful reference and inspiration for similar construction.
