摘　　要：刚体极限平衡法和强度折减数值方法在边坡工程稳定分析中发挥重要作用,已经取得了许多重要的研究成果。文中对以简化Bishop法、Morgenstern-Price法和通用条分法为代表的刚体极限平衡法的理论基础和计算过程进行了阐释,并将其与瑞典圆弧法、简化Janbu法及Spencer法等其他刚体极限平衡法的计算原理进行了对比分析,接着从计算方法、失稳判据和折减改进等方面对强度折减数值方法进行了分析,阐述了这2种方法在工程应用中的研究进展。边坡工程分析方法的进步,必将推动边坡工程治理向着精细化水平迈进。Rigid limit equilibrium method and strength reduction numerical method play an important role in slope sta⁃bility analysis,and many important research results have been obtained.In this paper,the theoretical basis and calculation process of the limit equilibrium method of rigid body represented by the simplified Bishop method,Morgenstern price meth⁃od and general slice method are explained,and series of contrast analysis will be carried out with the calculation principles of other limit equilibrium methods of rigid body such as Sweden Arc method,simplified Janbu method and Spencer method.Then the strength reduction is made from the calculation method,instability criterion and reduction improvement.The re⁃search progress of the two methods in engineering application is described.The progress of slope engineering analysis method will promote the slope engineering treatment to the level of refinement.
