摘　　要：采用一种均粒级配的透明土,对室内一维土柱积水入渗及排水过程进行观测,利用图片像素归一化强度与润湿液体饱和度之间的关系,可得到渗流试验过程中的连续水分剖面及封闭气体运移的定量化规律,为进一步合理预测非饱和土体实际入渗率提供试验观测数据.The infiltration and drainage process of indoor one-dimensional soil column was observed,with a uniform grain of transparent soil adopted. Based on the relationship between pixel intensity and wetting liquid saturation from the latest relevant research results, the continuous moisture profile and the migration law of entrapped air were obtained during the infiltration test, which could provide experimental observation data for predicting the actual infiltration rate of unsaturated soil in the further study.
