中文摘要：

通过渗滤液与清水在压实黄土柱中长期连续渗透对比试验,分析了在相同入渗条件下渗滤液与清水两者入渗率随时间的变化规律及其影响作用。试验结果表明,渗滤液入渗曲线呈波动状态,先后变化不大,清水入渗曲线则呈先升高再降低后又缓慢升高的变化趋势,渗滤液平均入渗率只有清水入渗率的12%。影响两者入渗率差异的根本因素是渗液性质导致的影响作用的不同。渗滤液入渗率影响作用主要包括微生物作用、水-岩相互作用与吸附、过滤等作用。清水入渗率主要受水-岩相互作用的影响。

英文摘要：

By comparing the experiments of leachate and rinsing infiltration in loess column, the varying trends of infiltration with time and their primary affecting factors under the same condition were analyzed. The experiments show that the curve of leachate infiltration appeared steady; the curve of rinsing infiltration rised at beginning, then falled, and slowly rised again ; and the rate of leachate infiltration was only 12 percent of that of rinsing infiltration during the experiments. The characteristics of infiltrating materials were the dominating factors that controlling the movement of infiltrating materials. The factors that influenced the leachate infiltrating variation included microorganism action, water-rock interaction, adsorption, and filtration, etc. But the rinsing infiltrating curve was mainly controlled by water-rock interaction.
