摘要
以五道岭隧道工程为背景,利用有限元软件对隧道穿越不同断层破碎带倾角进行分析,研究了不同断层破碎带倾角对隧道围岩位移的影响,研究结果表明:隧道围岩最大拱顶沉降量和周边收敛量都在断层破碎带处;断层破碎带倾角越大,隧道围岩越稳定。研究结果可为类似隧道穿越断层破碎带工程提供参考。
Taking Wudaoling tunnel project as the background,the finite element software is used to analyze the inclination of the tunnel crossing different fault fracture zones,and the influence of the inclination of different fault fracture zones on the displacement of the tunnel surrounding rock is studied.The research results show that:the maximum crown settlement and the peripheral convergence of the tunnel surrounding rock are at the fault fracture zone;the greater the inclination of fault fracture zone,the more stable the tunnel surrounding rock.The research results can provide reference for similar tunnels crossing the fault fracture zone.
