摘要： 综述了我国已建、在建和拟建的抽水蓄能电站与岩体初始应力场测试、应用资讯；初步研讨了当代抽水蓄能电站设计施工中应用岩体初始应力场的一些基本规律，包括:① 20座抽水蓄能电站实测岩体初始应力场存在高、中、低三类地应力水平；② 实测的岩体初始应力与埋藏深度的关系；③ 抽水蓄能电站厂房洞室长轴方向与地应力的关系; ④ 抽水蓄能电站的有压隧洞最小覆盖厚度;⑤ 地质断裂对抽水蓄能电站岩体初始应力约有30%～50%的影响。

Abstract: This review deals with constructed, under-construction, and awaiting construction pumped storage power station in China, and measurement and application of their rock mass initial stress field. Some basic laws of rock mass initial stress field during the design and construction of contemporary pumped storage power station, are preliminarily studied，including as follows: ①high, middle and low in-situ stress levels existing in the measured rock mass initial stress field; ②the general expression coinciding the three principal stresses changes in the region of 100-500m below the earth's surface; ③the relationship between the chamber long axis direction and the geo-stress; ④the equation of the minimum cover thickness of the PSP station; ⑤30%-50% effect on the rock mass initial stress caused by geological fracture.
