| 摘 要： | 针对大跨隧道在施工过程中,由于跨度较大而引起较多的不利因素导致施工进展困难,文章应用有限元方法对大跨度隧道的完整的开挖过程进行了动态模拟研究,模拟开挖采用能保证施工安全的双侧壁导坑法。对围岩的位移,初期支护的剪力、弯矩以及锚杆轴力动态变化进行监控,提出大跨度隧道施工中容易出现的问题及相应的解决措施。

| Abstract: | Because the large span of the tunnel will lead to construction difficulty during its excavation,this paper simulates the all process of tunnel excavation using double side guide adit method by FEM,caulates the displacement of rock mass,the shear force,the moment of initial liner and the axial force of the anchors,at last comes up with the the most possibility questions and give the advise. |
