摘要
以赵家屋隧道为例,建立了岩堆体隧道洞口浅埋段的多工况三维数值计算模型,完成了岩堆体隧道三台阶七步法施工过程的三维仿真计算,对不同结构参数下的隧道围岩与支护结构的受力变形规律进行了系统的分析和现场试验结果比较。
Taking the Zhaojiawu Tunnel as an example, this paper built the three-dimensional numerical calculation model for multi-condition shallow-buried section of a rock mass tunnel portal, and completed a three-dimensional simulation calculation for rock mass tunnel with three-stage-seven-step method and supporting structure under different structural parameters, and compared with the field test results.
