| 摘 要： | 本文采用三维有限元法对锦屏二级水电站引水隧洞区域的三维初始地应力场进行了反演回归分析,实测点处地应力计算值与实测值吻合较好,表明经过回归得到的地应力场是合理的,可为隧洞设计、稳定性分析和确定合理的施工方案提供基础性资料和科学依据。

| Abstract: | In this paper,three dimensional finite element method is applied to the inverse analysis of initial field stress for Jinping-2 hydropower station tunnel area.The calculated and measured values are consistent at the measured point,which shows that field stress inversion is reasonable.It can be taken to the basis of follow-up tunnel design and stability analysis. |
