Numerical Method of One-dimension for Rainfall Infiltration in Expansive Soil Slope of Excavation
Author(s): 
Pages: 158-161
Year: Issue:  2
Journal: JOURNAL OF TONGJI UNIVERSITY(NATURAL SCIENCE)

Keyword:  膨胀土非饱和渗流基坑边坡降雨入渗;
Abstract: 应用非饱和膨胀土一维降雨入渗模型,模拟膨胀土边坡在降雨入渗条件下的水分运移规律,通过数值计算,求得边坡在任意时刻任意位置的体积含水率;并分析了降雨强度、水分扩散率以及导水率变化对边坡水分运移的影响.计算结果可以用矩阵的形式和三维空间曲面的形式表示出来,方便应用.
