| 摘 要： | 采用三维非线性有限元反演回归分析计算方法，提出侧压力系数函数拟合方法，考虑了地质构造，地形地貌以及实测应力对初始应力场的影响。对蒲石河抽水蓄能电站地下厂房区域初始地应力场进行反演回归分析研究，实测点处附近应力分布的局部特性证明反演计算方法是合理的。

| Abstract: | Accordance to the practice of underground powerhouse of Pushihe Pumped Storage Power Station,and by using 3-D nonlinear finite element back analysis method,and considering effect of geological structure,topography and measured stress,back analysis of 3-D initial geostress is carried out.The results show that the method can reflect the impact of geological structure,topography on initial geostress,and it can also reflect the characteristics of stress distribution near measured points.The initial geostress as... |
