摘要
在深埋隧道的勘察钻孔中(DZ-松-1)采用水压致裂方法进行原地应力测量,确定出隧道围岩的现今地壳应力状态。结合隧道围岩的力学参数、工程地质特性等,运用三维有限元数值模拟技术对大丽线松树圆铁路隧道工程区进行了应力场模拟综合分析。给出了工程区地应力的赋存规律和基本特征。
Through the measurements of geo-stress in-situ,the crustal stress state in the region of the tunnel was determined(including the value and direction of in-situ stress).According to the measured in-situ stress state,the mechanical parameters of rock mass around the tunnel and the regional engineering geological conditions,the in-situ stress distribution in the engineering region was determined by the three-dimensional finite element method.
