摘要
基于吉莲高速永莲隧道工程,运用有限元的基本原理,对断层所在区域隧道围岩的应力应变状态进行数值模拟和分析,并深度讨论断层与隧道的相对距离以及断层的倾角对矩形隧道围岩稳定性的影响,分析总结断层附近隧道开挖矩形围岩应力的变化趋势、隧道沉降的大小、围岩破坏过程的相关规律,为以后类似工程提供理论参考。
Based on the Jilian Highway Yonglian Tunnel Project,using the basic principle of Finite Element Analysis,this paper makes a numerical simulation and analysis of the stress strain state of the tunnel surrounding rock in the area where the fault is located,the effect of the relative distance of the fault and the tunnel and the inclination of the fault on the stability of the rectangular tunnel,the change trend of the tunnel excavation rectangular surrounding rock stress,the size of the tunnel settlement,the relevant law of the surrounding rock destruction process,and provides theoretical reference for similar projects.
