中文摘要：

采用基于有限元和离散元有机结合的计算软件CDEM,将应变强度分布准则应用于数值分析中,对均质边坡的稳定性进行了分析。针对自然界中应变硬化型土体,引入一种土体强度随应力水平的增加而提高的强化机制,较好地模拟了边坡失稳过程中裂缝的发展过程。研究了应变强度分布准则下主控参数内摩擦角和最大剪应变强度对边坡稳定性的影响,得出了可以判断特定边坡稳定性的边坡临界状态曲线。通过单因素分析,得出内摩擦角对滑动面的位置起主要控制作用,最大剪应变强度对裂缝的发展起控制作用。总结得出了一种用破裂比评判边坡稳定性的方法。

英文摘要：

The stability of the homogeneous slope is analyzed based on strain strength distribution model by the organic combination of finite element and discrete element calculation software CDEM. With the introduction of a mechanism that soil strength increased with the stress levels increased, the development process of cracks in the process of slope failure is well simulated. Studied the impact of major parameters internal friction angle and maximum shear strain intensity on slope stability. Obtained a critical state curve of slope that can determine whether a particular slope stability. By univariate study, internal friction angle determines the position of the sliding surface and maximum shear strain intensity determines the development of cracks . Summarized a method that evaluated slope stability by rupture ratio.
