摘要
针对非饱和膨胀土边坡在降雨入渗下的稳定问题,结合镇江地区非饱和土的室内试验,对边坡的动态过程进行分析.分析了不同雨强、地下水位情况下降雨入渗的情况,对降雨入渗下的非饱和土边坡进行渗流场的数值模拟,得到非饱和土边坡降雨入渗下的若干规律,以及随降雨发展边坡稳定性的变化情况,为镇江地区的非饱和膨胀土边坡的稳定分析提供依据.
In order to solve the problem of unsaturated expansive soil slope under rainfall infiltration,combining with the laboratory test of unsaturated soil in Zhenjiang area,we analyze the dynamic process of slop,different rainfall intensity and underground water level conditions in the case of rainfall infiltration. For unsaturated soil slope,numerical simulation of seepage field under rainfall infiltration is carried out. Some rules of unsaturated soil slope under rainfall infiltration and side slope stability changes with rainfall development have been obtained.
