摘要
基于土壤水分运动连续性原理和非饱和土壤水分运动理论,本文对蒸发条件下粘土夹层的阻水阻盐作用效果给出了一种简单的定量评价方法——综合系数法。据此可以判断粘土夹层是否阻水阻盐及其阻水阻盐作用效果。
In this paper, based on the continuity principle and the dynamics theory of unsaturated soil water flow, a simple quant(?)tative to evaluate the method—the synthetic coefficient method is presented to evaluate the retardation effect of the intercalated clay bed on the movement of soil water and salt under evaporation. By using the method it can be determined whether a clay bed retards the movement of soil water and salt and how large the retardation effect is.
