摘　　要：地下厂房的厂区三维地应力场反演分析计算,是超大型地下洞室群围岩稳定研究的重要内容,本文以黄金坪水电站为例,根据实测地应力值和山体地形、地质条件建立三维地应力场反演计算模型,采用三维非线性有限元反演地下厂区初始地应力场,并对各种计算模型进行地应力插值计算。计算结果说明在主要建筑物处的反演计算应场基本与实测地应力点吻合,反演计算应力场基本上反应了实测应力点的基本规律。The analysis and calculation of three-dimensions ground stress inversion in the underground power- house is the important contents of the research of large underground caverns surrounding rock;This paper taking Huangjinping. Hydrop.ower Station as an e xample,established the three-dimensional stress field inversion calculation model,according to the measured geostress value,mountain terrain,geological conditions;a wide variety of computing models were situ stress interpolated with three-dimensional nonlinear finite element inversion undergound factor initial ground stress field ;the calculation results shows the inversion calculation stress field in the main building consistent with measured geostress point,which basically reflects the basic law of the measured stress point.
