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。
The limit balance method is used to evaluate the stability of slope for a long term, a new stability evaluation method （ stability analyses method of progressive failure of slope） is proposed, the Chenjialin landslide is taken as an example to evaluate the stability by limit balance and progressive failure methods, the comprehensive resistance - sliding force method, main thrust method, comprehen- sive displacement method and surplus displacement method are studied for the reinforcement of slope by progressive failure method, the results show： the main thrust method, comprehensive displacement meth- od and surplus displacement method are suitable to describe the stability of engineering slope, and can present the force and displacement characteristics, the comprehensive displacement method can describe the entire properties of slope, the main thrust and surplus displacement methods can present the surplus degree, and they are changeable with the displacement development, and the evaluation behaviors of slope are presented by these methods.
