摘　　要：抽水蓄能电站机组吸出高程大、安装高程低,厂房埋深处于下水库正常蓄水位以下百米以上的深度。尾水事故闸门能够及时阻断下水库及尾水隧洞的水流,以便于机组的检修,在紧急情况下可动水关闭,防止下水库水流淹没厂房。如何合理地设计尾水事故闸门,使其成为厂房名副其实的挡水墙,是抽水蓄能电站金属结构设计成功与否的关键所在。清远抽水蓄能电站尾水事故闸门的设计特点可供类似工程参考。Due to a high suction head and low setting position of the pumped-storage unit,the underground plant should usually be buried in 100 meters and above below the normal pool level of lower reservoir.The tail water emergency gate can timely block flow from lower reservoir and tailrace tunnel for normally facilitate the unit maintenance,and closing in dynamic water flow to prevent water submerged plant in emergency.So,how to rational design tail water emergency gate to worthy the name of water retaining wall of plat is the key to the success of the pumped-storage power station metal structure design.The design characteristics of tail water emergency gate in Qingyuan pumped storage power plant can be a reference for other similar projects.
