摘要： 具有裂隙性、膨胀性等特性的土质边坡稳定性研究需要考虑渐进性破坏问题。采用基于ABAQUS的有限元强度折减法，进行变形局部化和滑动面渐进式形成过程的有限元数值模拟，获得土质边坡稳定性的安全系数，及边坡坡角和土的剪胀角对边坡安全系数的影响。

Abstract: The progressive failure mechanism should be considered in the stability analysis of soil slopes with fissures and expansioncontraction characteristics. This paper presents the numerical analysis results of slope stability analyses using the strength reduction method. Local deformations as well as the development of the failure planes can be numerically simulated by ABAQUS. As a result, the factor of safety and the effects of the slope angle and the soil dilatant angle on the slope stability can be observed.
