摘要
通过在有限元软件Autodesk Simulation中建立隧道与周围岩体的二维模型并设定初始条件和边界条件,分析得到位移的变化规律.仿真分析结果表明,隧道整体结构的变形位移在底板处产生最大值,即为0.214 689m;拱顶位移相对较小,其值为0.013 554 2m,两侧直墙部分位移方向均指向隧道内部,位移大小为0.003 261 9m.
In this paper, two- dimensional model of tunnel and rock was established by the finite element software Autodesk Simulation, the initial conditions was set, then the conclusions were as following: deformation of tunnel had a maximum at the floor, the maximum value was 0. 214 689m; vault displacement was relatively small, its value was 0. 013 554 2m, both sides of the straight wall displacement direction were pointing to the inside of the tunnel, the displacement was 0. 003 261 9m.
