the results show that the internal friction angle of rock has importance affect on the displacement of surrounding rock for deep roadway when in-situ stress and support resistance all are certain.
分析结果表明,在地应力和支护阻力一定时,巖石的内摩擦角对深埋巷道围巖位移的影响最为明显。
the research results provide the reference value for the choice of the cohesion and internal friction angle of rock samples in the process of geo-engineering design and numerical simulation.
