%X 采用在粗粒土体表面喷洒聚丙酰胺溶液的方式构建阻渗层，来对毛细阻滞覆盖层结构进行改进，并通过室内土柱入渗试验对改进后毛细阻滞覆盖层土体的水分入渗规律阻渗性能进行分析，发现改进后覆盖层土体的储水能力提高，击穿时间得到延长，并有效减少了水分击穿后，细粒层土体的水分漏失速率，土体的防渗性能显著提高。<br />
The structure of capillary blocking mulch is improved by spraying polyamide solution on the surface of coarse soil. Then the water infiltration law and barrier performance of the improved capillary blocking mulch are analyzed by indoor soil column infiltration test. It is found that the water storage capacity of the improved mulch is improved, the breakdown time is prolonged, and the water loss rate of the fine soil is effectively reduced after the water breakdown.
