| 摘 要： | 隧道洞口附近覆盖较厚松散土层，进口处的隧道开挖会引起围岩应力状态变化，产生较大位移，且有可能导致其上部覆盖土层塑性区增大，出现明显的滑动面，进而产生洞口滑坡。通过对茶林预隧道进口处的隧道开挖采用三维有限元数值模拟，分析洞口滑坡的机理，并对洞口是否滑坡进行预测，为茶林顶进洞口处的安全施工提供参考。

| Abstract: | If there is thick and loose soil covering the opening of tunnel,the excavation of tunnel at the access will cause the change of stress state of surrounding rock to produce large displacement and probably lead to the enlargement of plastic zone of its upper covering soil generating obvious sliding plane and furthermore causing the landslide of opening.With the help of three-dimensional finite element numerical simulation for tunnel excavation at the access of Chalinding Tunnel,this paper analyzes the mechani... |
