Abstract: At present, there is no specific monitoring design specification for underground powerhouse of pumped storage power station. In combination with relevant design specifications and manuals, this paper summarizes the engineering practice of monitoring design of underground powerhouses of more than ten pumped storage power stations, and puts forward the purpose and principle of safety monitoring design of powerhouse system, as well as the monitoring design methods of surrounding rock, support structure, rock-bolted crane beam and other parts, which provides a reference for the safety monitoring design of underground powerhouse of pumped storage power station.

Key words: pumped storage power station, underground powerhouse, monitoring design

摘要： 目前，抽水蓄能电站地下厂房监测设计无专门的设计规范，笔者结合相关设计规范及手册，总结十余座抽水蓄能电站地下厂房监测设计工程实践，提出厂房系统安全监测设计的目的和原则，以及围岩、支护结构、岩壁吊车梁等部位的监测设计方法，为抽水蓄能电站地下厂房安全监测设计提供参考。
