摘要以猴子岩水电站地下厂房为研究对象，利用常规测试和微震监测技术，对开挖过程厂房高边墙围岩损伤区进行现场原位试验。基于一系列常规测试和微震监测结果分析，揭示了围岩变形破坏特征，得到厂房开挖卸荷过程围岩裂隙的萌生、发育和扩展的演化过程，分析了围岩开挖损伤区范围、裂隙演化与施工动态之间的相互关系，探讨了开挖损伤区的形成和演化机制。研究结果为猴子岩水电站地下厂房开挖、支护设计、围岩变形特性和地质资料分析提供了参考依据。相关研究工作作为地下厂房开挖、支护参数设计的重要依据，取得了较好的经济效益，对类似地下工程的设计施工有一定的参考价值和借鉴意义。

Abstract：It presents the in-situ tests on excavation damaged zone(EDZ) evolution of high sidewall surrounding rock mass in Houziyan hydropower station using microseismic monitoring and conventional testing methods such as multiple position extensometers，acoustic wave test and borehole TV. Firstly，through analyzing a series of conventional testing and microseismic monitoring results，deformation and failure characteristics of surrounding rock mass are revealed，and the evolution processes of surrounding rock fractures such as initiation，coalescence and extension are obtained during excavation unloading processes of underground powerhouse. Afterwards，the relationship among EDZ of surrounding rock mass，cracks evolution and construction status are also analyzed，which makes it possible for the whole procedure of cracks formation，development and close to be obtained. Finally，the depth of EDZ is recognized；the relationship between fractures evolution and construction progress is given；And the formation and evolution mechanism of EDZ is discussed as well. It will not only provide the direct data for geological exploration but also contribute greatly to excavation and support design and analysis of deformation behaviors of underground powerhouse. Some references can be thus provided for design and construction of similar underground engineering.

Key words： Excavation damaged zones underground powerhouse microseismic monitoring acoustic wave test borehole TV multiple position extensometers
