摘要:
为了评估基质势梯度对水分迁移的驱动效应，开展了非饱和土在基质势梯度作用下的水分迁移试验．试验结果表明，对于含水量分布于8%～24%的非饱和土而言，基质势梯度对非饱和土中水分迁移的驱动效应是显著的，且水分迁移量随着基质势梯度的增大而增加．进而建立了非饱和土中的水分迁移量与初始基质势梯度之间的统计关系式，二者之间大体上呈线性关系．
Abstract:
In order to assess the driving effect of matric potential gradient on moisture migration in unsaturated soil, the moisture migration experiment due to matric potential gradients was carried out. The driving effect of matric potential gradient was remarkable as to unsaturated loess with 8%~ 24% water content and the moisture migration quantity increase with the increase of the initial matric potential gradient. A statistical relationship between matric potential gradient and the moisture migration amount is established. The statistic relation shows that the moisture migration amount in unsaturated soil has a linear relation with the initial matric potential gradient in general.
