摘　　要：地下厂房系统是抽水蓄能电站工程的核心,施工期复杂地质条件下地下厂房围岩的稳定性更是关注的重点。本文以某抽水蓄能电站为背景,基于原型监测数据,结合地质、施工等情况,对施工期复杂地质条件下的厂房围岩变形性态进行分析,了解地下洞室不同部位在施工过程中影响围岩稳定的主要因素,为其他类似工程的设计和施工提供参考。The underground powerhouse system is the core of the pumped storage power station, and under the complex geological conditions, the stability of the surrounding rock of the underground powerhouse is the focus of attention.In this paper, taking a pumped storage power station as the background, a prototype based on the monitoring data, combined with geology, construction conditions and so on, the deformation behavior of the surrounding rock of the factory building under the complex geological conditions during the construction period is analyzed, and the main factors affecting the stability of the surrounding rock in the construction process of the underground caverns are understood, providing the reference for the design and construction of other similar projects.
