摘　　要：岩体结构面组合对巷道围岩稳定性的影响研究 ,一直是一个热点研究课题 ,不同的岩体结构面组合对巷道围岩稳定性的影响及其破坏的形式与规模都是不同的。本论文根据某具体煤矿项目的工程地质条件 ,采用离散元法模拟分析了节理不同方位组合对巷道稳定性的影响及其破坏形式 ,并得出了一些有益的结论 ,用以指导煤矿开采施工。The study on the tunnel stability due to discontinuities in rockmass has been a hot research subject in the engineering geology field. Based on the engineering geology conditions of a concrete coal tunnel, the DEM method was used to simulate and analyse the affection on tunnel stability due to the joint array by different styles. Some beneficial results were gained and were used to guide the construction in coal tunnel projects.

关 键 词：结构面组合 围岩稳定性 离散元法
