摘要:通过模型实验,利用电阻法测定了降雨入渗土质斜坡的入渗深度和入渗时间,分析了
雨水入渗土体内的深度及需要的时间,寻找雨水入渗深度对斜坡破坏的影响规律。试验结果
表明,在浅层范围内,雨水入渗深度与入渗时间基本呈线性增加关系,离坡面深 5cm 范围内,
不同位置处的入渗时间和入渗规律基本相同,离坡顶越近,入渗深度越浅。因此,本试验研
究对降雨情况下土质斜坡防治有一定的指导作用。

Abstract: Through model test of soil slope, the infiltration depth and infiltration time were
measured under sustained rainfall into soil slope by Resistance method. With the analysis of
infiltration depth and related time, the influence of infiltration depth to slope failure could be
obtained. The experiment results show that the infiltration depth increases linearly with the
infiltration time under sustained rainfall in the shallow range of soil slope. Within 5cm from slope
face, the infiltration time and infiltration law is basically the same at different locations. The
infiltration depth is shallower at the top of the slope. Therefore, the experiment study could have a
guiding role on the prevention of soil slope failure under sustained rainfall.
