摘　　要：介绍了在蒲石河抽水蓄能电站引水隧洞下平段断层处理工程中,采用600 MPa级高强钢衬管处理方案的确定和实施过程。在克服安装工期紧、空间狭小、焊接难度高和低温环境施工等不利条件的影响,提前完成了钢衬管的安装,解决了断层渗水问题,保证了电站的运行安全,可为类似工程的施工提供借鉴。The 600 MPa high strength steel liner pipe is used in the faults treatment of lower horizontal sections of headraee tunnels in Pushihe Pumped-storage Power Station. The determination of treatment program and the installation of steel liner pipes are described. After overcoming the adverse impacts of shorter eonstruetion duration, narrower space, diffieuh welding and lower temperature, the installations are completed in advance, and the water leakage from the faults is eliminated. The treatments guarantee the safe operation of station, and can be as reference for similar projects.
