摘　　要：吉沙水电站采用引水式开发,为高水头、小流量、长距离引水发电工程,具有引水隧洞长、调压井高、高压管道压力大等特点,因此调压井布置和设计是整个引水系统设计乃至电站安全稳定运行的关键,对引水隧洞和高压管道具有承前启后的作用。通过对调压井位置、型式选择,水力学和结构设计计算,确定了调压井布置,保证了工程安全。Jisha Hydropower Station is diversion-type developed with high head, low flow and long diversion distance. The project has a longer diversion tunnel, deeper surge shaft and high-pressure penstock. The layout and design of surge shaft is the key of diversion system design as well as the safe and stable operation of the station. The surge shaft design is studied from the aspects of location selection, type selection and hydraulics and structural calculations for guarantying the safety of project.
