| 摘 要： | 通过FLAC软件模拟了软弱夹层对深部巷道稳定性影响,主要模拟研究顶部分布有软弱夹层的回采巷道的围岩稳定性,总结了软弱夹层分布距离与巷道围岩位移、围岩塑性区及应力的关系,得出了软弱夹层的不同位置对围岩变形、应力影响的一些量化成果。

| Abstract: | Simulates the influence of weak interlayer has on deep roadway stability by FLAC software,mainly simulates the deformation degree of roadway surrounding rock while the relative position of weak interlayer and roadway changes.Summarizes the distribution of weak intercalation distance and displacement of surrounding rock,rock plastic zone and the stress of the relationship.Then,obtaining some quantitative results about effects on surrounding rock strain and stress while the weak interlayer is in different positions. |

| Keywords: | weak interlayer interlayer position degree of influence comparative analysis |
