摘　　要：基于水泥、粉煤灰、黏土土添加物潜入土壤模拟入渗试验,分析了细颗粒物质种类和添加量对土壤水分入渗过程的影响。结果表明,不同添加物显著影响土壤水分入渗能力,其阻渗能力为:水泥>黏土>粉煤灰;细颗粒物质添加量对土壤水分的入渗能力有一定影响,但影响不显著。添加物改变了土壤孔隙度,影响土壤表层水分运移的部分通道,影响入渗过程。Based on simulation infiltration experiment of fine particulate matter additives such as cement,fly ash,clay sneaking into soil,the influence of type and content of fine particulate matter on soil water infiltration process was analyzed.The results showed that different additives had an obvious impact on soil water infiltration capacity and its ability of preventing permeability in descending order was that cement〉clay〉fly ash;There was a certain influence of additives content on soil water infiltration ability,but the influence was not significant.Additives could change the soil porosity,and affect part of the soil moisture migration channel and infiltration process.
