摘要
以重庆市轨道环线下穿大公馆立交边坡工程为背景,采用有限元软件MIDAS/GTS计算分析轨道隧道下穿岩质高边坡的受力特性,模拟轨道隧道施工过程,从位移、应变、应力等方面分析轨道隧道下穿对岩质高边坡的影响,为今后类似工程提供参考。
With the background of the project that Chongqing rail line passing under Dagongguan intercross side slope, this paper takes finite element software MIDAS/GTS to calculate and analyze mechanical characteristics of rail tunnel passing under rock high side slope, simulate the rail tunnel construction process and analyze influence to rock high side slope by rail tunnel passing under in aspects of displacement, strain and stress, etc. , so to provide reference for future similar projects.
