摘要
采用极限平衡分析法,建立了能考虑降雨入渗的饱和—非饱和边坡稳定性分析方法,对降雨条件下边坡稳定性变化规律进行了分析,计算结果表明,抗剪强度参数、边坡初始状态都对边坡稳定性具有明显影响,降雨造成的孔隙水压力变化比自重增大对边坡稳定性的影响更大。
Based on the limit equilibrium method and unsaturated-saturated seepage model, the stability analyzable model is established to study the rainfall effects on the slope stability. The results show that the parameters of shear strength and initial pore water pressure distribution have important impacts on reducing the slope stability. And the increase of the pore water pressure induced by rainfall infiltration will reduce the slope stability more compared with the increase of the soil dead weight.
