摘要
应用ANSYS有限元软件,建立三维有限元模型,通过计算主要分析高速公路隧道开挖引起的围岩位移场和应力场的变化情况和其对供水隧洞的影响程度,对供水隧洞衬砌结构的位移及内力变化进行分析,进而评估对供水隧洞的安全影响。
With the application of ANSYS software ,three-dimensional finite element model was built;by cal-culating it mainly analyzes the change situation of surrounding rock displacement and stress field caused by high way tunnel excavation and their impact on the water supply tunnel;water supply tunnel lining structure displacement and internal forces are analyzed in order to assess the impact on the water supply tunnel ’s safe-ty.
