通过观测成层性结构土毛细水上升高度和蒸发,研究土层结构对毛细水上升高度和地下水蒸发的影响,并对这些影响因素进行机理分析。研究结果表明,如果毛细水能透过下部土层迁移到上层,毛细水上升高度则由上层土性质所决定;土壤中夹层厚度如果大于该夹层土毛细水所能上升的最大高度,毛细水不能透过夹层迁移到上部土层参与蒸发。
By observing the rising height and evaporation of the capillary water in the stratified structure, the influence of soil structure on the height of capillary water and the evaporation of groundwater was studied, and the mechanism of these factors was analyzed. The results show that if capillary water can migrate to the upper layer through the lower soil layer, the capillary water rise is determined by the properties of the upper soil layer. If the thickness of the interlayer in the soil is greater than the maximum height at which the interlayer capillary water can rise, the capillary water can not Migration through the interlayer to the upper soil involved in evaporation.
