【摘要】 分析了隧道及地下工程围岩位移的极限状态,结合乌鞘岭隧道软弱围岩地质情况,采用ANSYS有限元法对软弱围岩隧道稳定性进行数值模拟,说明用极限分析法来模拟隧道极限位移是一种很有前途的计算方法。更多还原

【Abstract】 The ultimate displacement situation of tunnel and underground engineering surrounding rocks is analyzed,combining with Wushaoling tunnel under soft wall rock,the numerical simulation of the weak adjacent formation tunnel stability is analyzed by ANSYS,and explained simulates the tunnel limit displacement with the limit analytic method is one kind has the future computational method very much.更多还原
