摘要
以某大型水利工程拟建地下厂房为典型实例 ,应用二维非线性有限元分析方法 ,研究大跨度、高边墙地下厂房区二次应力场分布规律 ,并评价围岩的稳定性。
Taking the underground powerhouse in a huge hydropower station as an example,the authors studied distribution pattern of the secondary stress field of surrounding rock mass with nonlinear finite element method of the large-spaned underground powerhouse with high side wall and evaluated the stability of surrounding rocks.
