摘要
文章研究了传统路基边坡稳定性分析方法的特点,指出了路基边坡稳定性分析长期使用的极限平衡法的若干缺点。同时,介绍了一种新的条分法及几种新的边坡稳定系数计算方法,并使用新方法及新型稳定系数对实例中路基边坡稳定性进行了分析。实例分析结果表明:新条分法克服了传统路基边坡稳定分析法的若干缺点;新型稳定系数可体现出路基边坡发生破坏的渐变过程中力和位移的演化规律。在路基边坡稳定性分析领域,文中使用的方法是值得借鉴的。
In this paper,the characteristics of the traditional method for analyzing the stability of roadbed side slope are studied,the shortcomings of the limit equilibrium method which has been used for long term are pointed out.Meanwhile,a new slice method and several new stability coefficient calculation methods are introduced in the paper,and the new methods are applied in calculating and analyzing the stability of roadbed slope in the practice.The research results show that:the new slice method overcomes some disadvantages of the traditional limit equilibrium method,and the new stability coefficient can show the evolution law of force and displacement in the process of gradual failure of roadbed slope.In the field of roadbed slope stability analysis,the method used in this paper is worthy of reference.
