| 摘 要： | 基于等分圆弧滑面的简化条件,采用土塑性极限分析理论,建立了土质边坡极限分析模型,并推导得到了土质边坡稳定系数计算公式。该方法考虑了圆弧滑面的内能耗散率作用和边坡土体自重荷载、地震惯性力及孔隙水压力所做的外功率作用,可以解决土质边坡稳定性分析问题,是一种改进的土质边坡稳定性评价极限分析方法。

| Abstract: | Based on the simplified assumption of equidistant circular slip surface,the model of limit analysis for soil slope stability can be established,the formula for computation of safety factor can be obtained when the theory of soil plasticity limit analysis is used.The method had considered not only the effect of the energy dissipation rate produced in the slip surface,but also the effect of the work rate produced by selfweight,seismic force and pore water pressure.It is a modified method of soil plasticity limit analysis,and can be used to evaluate the stability of soil slope. |
