摘要
采用地下工程专用软件 2d -б对皮峁沟隧道深埋段与进口偏压段施工过程中围岩和支护结构的变形和内力进行了仿真分析 ,分析结果表明 ,提出的设计参数是安全可行的 ,可供其它类似工程参考。
Analyze the deformation and internal force of surrounding rock and support structure during construction for deep depth section and shallow depth uneven pressure section of Pimaogou tunnel by using 2-D FEM,analysis results indicate that the design parameters brought forward by the author is feasible,and can be used as a reference for other analogousengineering.
