摘　　要：调压井是发电引水系统中常用的保证供电稳定及防止水锤破坏压力管道的建筑物,在发电洞运行过程中它能保证供电稳定及防止水击压力对压力管道的破坏。通过介绍AT水利枢纽调压井的位置选择、稳定断面计算方法、涌波计算方法及工况组合,确定调压井的运行方式和调压井结构形式的设计,总结了大流量、高水头、大直径调压井的设计方法。Surge shaft is a building commonly used in power generation and water diversion system to ensure power supply stability and prevent water hammer from damaging pressure piping.During the operation of power tunnel,it can guarantee the stability of power supply and prevent damage to pressure piping caused by water hammer pressure.In this paper,by introducing the location selection of surge shaft,calculation method of stable section,surge calculation method and operation combination of AT hydro-junction,the operation mode of surge shaft and the structural design of surge shaft are determined,and the design method of surge shaft with large flow,high head and large diameter is summarized.
