| 摘 要： | 基于室内一维积水入渗试验结果,分析了土体类型、干密度和初始含水量对土体入渗率的影响.试验结果表明:土体的入渗率随土样中粘性颗粒含量的增加同样逐渐减小;随干密度的增加逐渐减小;当干密度较小时,随初始含水量的增加逐渐增加,当干密度较大时,随初始含水量的增加逐渐减小.

| Abstract: | Based on one-dimensional ponding water infiltration in laboratory,the influences of cohesive particles content,dry density,and initial water content on infiltration rate are analysed.Soil infiltration rate decreased with the increase of cohesive particles content and dry density;with the decrease of initial water content at low dry density,and with the increase of initial water content at high dry density. |

| Keywords: | one-dimensional ponding water infiltration cumulative infiltration infiltration rate |
