【摘要】：边坡稳定性分析长期以来采用的是极限状态理论,近来一种新的稳定性分析方法 (边坡渐进破坏稳定性分析法)被提出,以陈家岭公路边坡治理为实例,研究了边坡渐进破坏稳定性分析法中的综合下滑力抗滑力法、主推力法、综合位移法和富余位移法在治理中的应用,研究结果表明:主推力法、综合位移法和富余位移法能够应用于工程实践,其中,主推力法、综合位移法和富余位移法分别能对边坡力和变形行为进行描述,综合位移法是对边坡特征的描述,而主推力法与富余位移法是对边坡富余程度的描述,三种稳定系数均随边坡变形的演化而变化,可以描述边坡的渐进演化破坏特征。
[Abstract]:The limit state theory has been used in slope stability analysis for a long time. Recently, a new stability analysis method (slope progressive failure stability analysis method) has been proposed, taking the slope treatment of Chenjialing highway as an example. The application of comprehensive sliding force method, main force method, comprehensive displacement method and surplus displacement method in slope progressive failure stability analysis is studied. The results show that: main push force method. The comprehensive displacement method and the residual displacement method can be used in engineering practice. Among them, the main force method, the comprehensive displacement method and the residual displacement method can describe the slope force and deformation behavior respectively. The comprehensive displacement method is the description of the slope characteristics, while the main force method and the residual displacement method are the description of the slope surplus degree. The three stability coefficients all change with the evolution of the slope deformation. The progressive evolution failure characteristics of slope can be described.
