摘要
以某矿-910 m水平某段巷道为工程背景,利用FLAC~(3D)数值模拟研究深部巷道围岩分区破裂现象,分析总结了模型网格精度、初始地应力及侧压系数对深部高应力巷道围岩分区破裂现象的影响。
Taking a mine in-910 m level in a tunnel as the engineering background, use the FLAC~(3D) numerical simulation of deep roadway surrounding rock zonal disintegration phenomenon to analyze and summarize that the model grid resolution, initial stress and lateral pressure coefficient of high stress roadway surrounding rock should influence the zonal disintegration phenomenon of deep.
