| 摘 要： | 采用三维弹塑性有限元法对某水电站地下洞室群三维初始地应力场进行了反演回归分析。计算结果表明，厂区初始地应力场分布规律合理，实测点处地应力计算值与实测值吻合较好，可以作为后续数值分析和地质力学模型试验的依据。

| Abstract: | In this paper, three-dimensional elastic-plastic finite element method is applied to the inverse analysis of initial field stress for underground cavities of a hydropower project. The results show that the distribution of initial field stress is reasonable, the calculated and measured values are consistent at measured point. It can be considered as the basis of follow-up numerical analysis and the geological model test. |
