中文摘要:
      首先用离散元软件UDEC计算出顺层岩质边坡稳定性安全系数在不同因素影响下的大小,再依据该结果用灰色关联方法分析7个不相关因素(岩层倾角、岩层厚度、岩体密度、层面内摩擦角、层面粘聚力、岩体内摩擦角、岩体内聚力)对顺层岩质边坡安全系数敏感性影响。研究结果表明:层面粘聚力和岩体内聚力对顺层岩质边坡稳定性影响比较敏感,岩层倾角、岩体密度、岩层厚度以及层面内摩擦角次之,岩体内摩擦角相比之下较不敏感。该结论为以后顺层岩质边坡的设计及其治理提供了评价依据。
英文摘要:
      Firstly, the bedding rock slope's stability coefficients under different influence factors are calculated by discrete element software UDEC. According to the results, the sensitivity of the bedding rock slop's stability coefficients are analyzed by the grey correlation method with seven unrelated factors (the dip angle, thickness of strata, rock density and level friction angle, surface cohesion, rock internal friction angle, rock cohesion). Furthermore, research results show that the level of cohesion and rock cohesion are sensitive to influence the bedding rock slop's stability. Comparing to the pervious, dip angle of strata, rock density, thickness of strata, level friction angle are lesser sensitive. The internal friction angle of rock mass is the least sensitive. The conclusion provides a basis for the design and management of the bedding rock slope in the future.
