摘　　要：旨在通过数值模拟方法,深入探究软硬互层顺倾岩质边坡的稳定性问题,并分析黏聚力、内摩擦角以及岩层软硬分布对边坡安全系数和滑动面位置的影响规律。研究结果表明:随着层面黏聚力和内摩擦角的增大,软硬互层顺倾岩质边坡安全系数增大,且滑动面位置越深,边坡越稳定;边坡下层岩性为硬岩时,边坡安全系数高,滑动面位置更深,稳定性强。研究结果揭示了顺倾岩质边坡失稳过程和变形模式,可为顺倾岩质边坡稳定性分析提供一定的参考价值。This paper aims to deeply explore the stability of bedding rock slopes with interbedded soft and hard layers through numerical simulation methods,and analyze the influence laws of cohesion,internal friction angle,and the distribution of soft and hard rock layers on the slope safety factor and the position of the slip surface.The results show that with the increase of the bedding cohesion and internal friction angle,the safety factor of the bedding rock slope with interbedded soft and hard layers increases.Moreover,the deeper the position of the slip surface,the more stable the slope is.When the lower layer of the slope is hard rock,the slope has a higher safety factor,a deeper slip surface position,and stronger stability.The research results reveal the instability process and deformation mode of the bedding rock slope,providing certain reference value for the stability analysis of the bedding rock slope.
