摘要

通过室内层施保水剂的毛管水上升模拟试验,分析了层施保水剂厚度对毛管水上升特性影响,结果表明:(1)相同毛管水上升高度下,层施保水剂厚度越大,其地下水补给量越大;(2)相同供水时间下,层施保水剂厚度越大,毛管水上升高度越小;(3)供水结束时,在下层土壤湿润范围,距供水面相同距离的土壤含水量随着层施保水剂厚度的增大而增大,在土壤上层湿润范围,相同位置的土壤含水量则相反。以上研究结果可以为高地下水位地区减轻渍害提供理论依据。
        Through the indoor simulation experiment on the upward movement of capillary water after the application of the layer-applied aqusorb,the impact from the thickness of the layer-applied aquasorb on the characteristics of the upward movement of capillary water is analyzed herein.The result shows that: 1.under the same height of the upward movement of capillary water,the bigger the thickness of the layer-applied aquasorb is,the more the supplement from ground water will be;2.under the same water supply time,the bigger the thickness of the layer-applied quasorb is,the less the height of the upward movement of capillary water will be;3.when water supply shuts off,the soil water content at a same distance to the supplied water table increases along with the increase of the thickness of the layer-applied aquasorb within the wet scope of the lower-layer soil;whereas,it is reverse for the soil water content within the wet scope of the upper-layer soil.The research result can provide a theoretical basis for alleviating the water logging disaster in the area with high groundwater level.
