如何确定可供工程应用的岩体初始应力场，是岩土工程中一个急需解决的实际课题。在清远抽水蓄能电站三维有限元地质模型上施加不同的边界荷载，模拟地应力场的不同影响因素所产生的初始应力，并在现场地应力实测资料基础上，运用多元回归反演方法，预测了包括重要工程部位在内的整个工程区岩体地应力场。

How to determine the in-situ stress field available for the engineering practice is an urgent practical problem of the geotechnical engineering. In tests, different boundary loads are exerted on the 3-D FEM geological model of Qingyuan Pumped Storage Power Plant in order to simulate the in-situ stress owing to diverse influence factors. And then on the basis of the field measured in-situ stress data, in-situ stress field in the whole rock mass including the major project locations is obtained by the inversion method of multivariate regression.
