摘要
选用 2 D—σ有限元计算软件对深部巷道围岩在构造应力场中的稳定性进行了数值分析 ,着重讨论了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 。
This paper applied the finite element software of2 D-σ to make a numerical analysis of deep roadways stability in structural stress field. It emphasisly discussed the character of deformation,the development character of yield region,the stress distribution character and the dynamic evolution procession of deep roadways surrounding rockmass.The paper demonstrated the failure mechanism of surrounding rockmass and the dynamic relation between the structural stress and deformation and failure.It also presented the rational supporting countermeasur
