摘　　要： 将强度折减有限元法与ABAQUS软件相结合,借助ABAQUS的强大非线性功能和丰富的单元库,建立了平面破坏型边坡有限元分析模型。充分利用ABAQUS软件强大的后处理功能,动态显示广义塑性应变和塑性区的开展情况,以塑性区的贯通作为判据,通过不断调整折减系数确定最终安全系数,以此对边坡稳定性进行判定。通过实例验证了其计算结果和极限平衡法具有较好的一致性,它表明该法是合理可行的,为快速有效地分析边坡稳定问题提供了一种思路。 The shear strength reduction finite element method with ABAQUS software is combined,and the powerful non - linear function and rich cell library of the ABAQUS software is used, a finite element analysis model for the failure in the plane of the slope is then established. Taking full advantage of powerful post-processing functions by using ABAQUS software, dynamically displaying the development situation of the generalized plastic strain and plastic zone, taking the running through of the plastic zone as a criterion, through continuous adjustment of reduction factor to determine the ultimate safety factor in order to determine the stability of the slope, the calculated resuits has a good consistency with the limit equilibrium method, it shows that the way is reasonable and feasible. At the same time, it offers a kind of thought for analyzing the slope stability quickly and efficiently.
