【摘要】 边坡稳定性分析是岩土工程领域的重要研究课题,近年来边坡事故多发边坡稳定性问题受到高度重视。刚体极限平衡法和有限元强度折减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研究成果。文中对以简化Bishop法、M-P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,同时结合算例对有限元强度折减法等计算机数值计算方法的基本原理、主要特点和功能优势进行了分析并对比。通过列举前人的研究进展和工程实际应用,总结各种方法的适用范围和局限性。最后指出,随着边坡技术的进步,应发展多种分析方法相结合的复合分析法和随机方法与模糊方法相结合的可靠度分析法等新型边坡分析方法。更多还原

【Abstract】 Slope stability analysis is an important research topic in the field of geotechnical engineering. In recent years, slope stability problems with frequent accidents have received high attention. Rigid body limit equilibrium method and finite element strength reduction method play an important role in slope stability analysis, and many important research results have been obtained. In this paper, the theoretical basis and calculation process of rigid body limit equilibrium method represented by simplified Bishop method, Morgenstern-Price method and general strip method are explained, and the basic principle, main features and functional advantages of finite element strength reduction method are analyzed and compared with examples. Finally, it is pointed out that with the progress of slope technology, new slope analysis methods should be developed, such as composite analysis method combined with various analysis methods and reliability analysis method combined with random method and fuzzy method.更多还原
