| 摘 要： | 针对汾柳高速公路离石隧道在不同施工方法下围岩和隧道支护结构的受力问题,运用有限元程序ANSYS6.1对三导洞法和上下台阶法进行了动态数值模拟,建立了不同施工工序下围岩的位移场和应力场,并以此对这两种施工方法进行了对比分析,得出三导洞法较优.对隧道的施工具有一定的指导意义.

| Abstract: | Based on the Lishi double-arch tunnel engineering of the Fenliu highway,this paper studies the mechanical problem of the excavating and supporting during the double-arch tunnel construction in the loess.The three-heading construction method and the benching tunneling construction method have been simulated with the application of ANSYSV6.1 FEM program.The stress and displacement fields distribution under different construction procedure is obtained.The three heading construction method is proved to be the better one through the analysis and comparision.The results have important significance for guiding double-arch tunnel construction in the loess. |
