摘要
选用 2D—σ有限元计算软件对深部巷道围岩在复合应力场中的稳定性进行了数值分析 ,着重讨论深部巷道围岩的变形特征、塑性区发育特征、围岩应力分布特征和围岩破坏机理 。
The finite element software of 2D—σ is used to make a numerical analysis of deep roadway's stability in compound stress field.In the paper,the characteristics of deformation and the stress distribution,the development features of plastic region and the failure mechanism of surrounding rockmass of deep roadways is emphatically discussed.Also,the rational supporting countermeasures are presented.
