本文采用三维仿真数值模拟对隧道浅埋偏压段围岩不同施工方法进行了数值模拟,分析了围岩和支护结构体非线性力学行为的地应力场、位移场,确定了合理的开挖方案。
In this paper, three-dimensional numerical simulation is used to simulate the different construction methods of surrounding rock of shallow buried section of tunnel. The geomechanical field and displacement field of nonlinear mechanical behavior of surrounding rock and supporting structure are analyzed, and reasonable excavation Program.
