摘要
采用ANSYSV5 .6版有限元分析程序对连拱隧道可能采用的施工方案进行了二维有限元分析。模拟了 3种开挖方案 ,获得了连拱隧道在采用不同开挖方案施工时各阶段围岩的应力、应变状态以及隧道支护结构中的内力变化情况 ,通过对比、分析 。
Three construction schemes for double-arch tunnels have been simulated with the application of ANSYS V5.6 FEM program. The stress and strain state of surrounding rocks, internal forces of tunnel support structure for each construction scheme are obtained by 2D calculation. Some solutions are obtained based on comparing and analyzing those mentioned above.
