摘　　要：边坡稳定性分析是公路工程的一个重要领域,目前工程中常用的方法为极限平衡法,而学术研究领域内则使用数值模拟法的频率较高。运用有限元强度折减法,结合数值软件ABAQUS强大的非线性分析功能,对某公路高边坡进行了稳定性分析。由于折减系数与传统极限平衡法中的安全系数有着相同的意义,因而可进行对比分析,结合两者的优点,实现对工程更加有效的指导。Slope stability analysis is an import subject of road engineering. Currently, limit equilibrium method is commonly used in engineering, while numerical simulation method is used more frequently in academic study. This paper applied strength reduction FEM, combining with the powerful function of nonlinear analysis by software ABAQUS, to analyze stability of high slope along a highway. Since the reduction factor has the same meaning as the safety factor in limit equilibrium method, comparative analysis may be carried out, through which the both methods＇ advantages could be combined, implementing effective guidance in engineering.
