摘要
为了分析降雨入渗对边坡稳定的影响,建立了ABAQUS二维有限元分析模型,通过对材料性质、分析步及加荷参数的调整,对比了降雨前后边坡土饱和度、孔压、应变、沉降及水平位移的变化。结果表明:随着降雨时间的延长,边坡有滑动变形趋势,极易导致滑坡的发生。
The 2D finite element model for the soil slope stability analysis is developed using ABAQUS. Through the adjustment of material prop- erties, the analysis step and the loading parameters, the comparison results of the soil saturation, pore pressure, strain, settlement, horizontal displacements are made for the slope stability before anti after infiltration. The analysis results show that with the increasing time period of infihra- tion, the soil slope has a tendeney of slide after the infiltration, it is easy to result from landslide.
