摘要
运用有限元分析软件对天恒山隧道Ⅵ级围岩加宽带施工进行了仿真模拟,分析了加宽段的开挖变形行为和衬砌应力、围岩位移和应力特征等,提出了土质施工建设中需要特别关注的几个问题,为隧道的安全建设提供了基础的资料,确保了天恒山隧道加宽洞段的施工安全,并为今后国内类似工程提供参考。
By using software of finite element analysis,the author simulated construction of wall rock widens location of Tian Heng mountain tunnel VI.Then,the author analyzed deformation behaviors of excavation,lining stress,displacement of wall rock and features of stress.Finally,the author put forward problems which were needed concern in construction of soil engineering,which guaranteed the safety of construction of widen location of Tian Heng mountain tunnel provided basic material and reference for similar projects.
