摘要
基于乌鞘岭隧道现场量测数据,采用ANSYS有限元软件对围岩弹性模量和侧压力系数进行了反分析.根据所求得的参数值,计算得到了二次衬砌的内力和安全系数.计算结果表明,分析断面的安全性是足够的.
In view of the measurement data of Wushaoling Tunnel in situ, the elastic modulus and lateral pressure coefficient of the surrounding rock were calculated by use of the ANSYS FEM software. According to these parameters, the internal forces and security coefficients of the tunnel lining were computed. The results show that the security of the analytic section is sufficient.
