摘　　要：蒲石河抽水蓄能电站引水隧洞下平段发育多条断层,属Ⅲ～Ⅳ类围岩。其中,规模最大的F3断层及上、下盘影响带宽约22～25 m。在开挖过程中,断层渗水严重,围岩局部稳定性差。介绍了蒲石河抽水蓄能电站引水隧洞下平段断层处理方案的确定过程,为类似工程的处理提供借鉴。The lower horizontal sections of headrace tunnel, in Pushihe Pumped-storage Power Station passes through some faults, in which, the width of the largest F3 fault zone is about 22-25 m. The water seepage is serious during tunnel excavation. The surrounding rock of headrace tunnel has poor stability. The determination of treatment program for these faults in project design is introduced herein. The practice provides a reference for the design of similar projects.
