摘　　要：CCS水电站输水隧洞在TBM施工过程中,遇到了砂岩崩解砂化、断层破碎带塌方、突涌水、围岩失稳等不良地质条件,导致了掘进速度缓慢、卡机等不良后果。经过采取有效的处理措施,TBM通过了不良地质段,为输水隧洞的如期完成提供了保障。The sandstone disintegrating, fault fracture zone collapse, water inrush, surrounding rock instability were encountered in TBM construction process, which leading to the low excavation speed, TBM blocked and other adverse consequences. The TBM crossed the unfavorable tunnel section by taking effective measures, which provided a guarantee for completion of water conveyance tunnel timely.
