摘要

根据室内非饱和土的渗透试验得出的非饱和土的渗透参数，针对黄河下游堤防典型的非饱和土边坡，采用有限单元法系统地分析了堤防非饱和土边坡在降雨和洪水作用下的非饱和渗流场特征，并得出降雨与洪水对非饱和粉质黏土边坡渗流场的改变范围，该范围的大小为浸润线移动前方2 m之内。进一步分析了降雨与洪水共同作用对黄河下游堤防边坡非饱和渗流场的影响，分析结果表明降雨程度的大小和持续时间的长短直接影响着洪水对非饱和渗流场改变的难易程度。

Abstract

The permeability coefficient of the unsaturated soil can be got from the seepage test with the triaxial test instrument for unsaturated soils controlled by stress and strain in the laboratory. Based on this

under the environment of rain and flood we analyze the variability of the seepage field of unsaturated levee slopes in the lower reaches of Yellow River with the finite element method. From this we get the extent influenced by rain or flood infiltration in front of the saturation curve. The extent is about 2 meters. We analyze the co-operated influence of rain and flood infiltration and get that whether the flood infiltration can easily change the seepage field or not is determined by the rainfall intensity and rainfall duration.
