摘  要：
为了研究淡水与微咸水连续和间歇入渗特性的差异,采用矿化度1.33 g/L的淡水与矿化度3 g/L的微咸水,在黏质土壤条件下进行了一维积水连续入渗及间歇入渗试验。研究结果表明,采用微咸水入渗可以改变土壤的结构特性,从而增大土壤的入渗能力;利用一维代数入渗模型对试验资料进行处理,结果表明模型可以比较精确地描述微咸水入渗过程;入渗水为淡水时,间歇入渗减渗,而入渗水为微咸水时,间歇入渗增渗;间歇入渗的循环率不同,其减渗效果及增渗效果都略有差异。

摘  要：
In order to research the difference between continuous infiltration and intermittent infiltration of fresh water and saline water,one-dimensional infiltration experiments of continuous and intermittent water with salinity of 1.33g/L for fresh water and 3g/L for saline were carried out in clay soil.The results showed that saline water can influence soil structural characteristics and enhance infiltration capacity.One dimensional infiltration modeling analysis showed that the model is able to describe the process of saline water infiltration exactly.Intermittent infiltration of fresh water had an effect of reducing infiltration,however,intermission infiltration of saline water had an effect of increasing infiltration.There existed slight difference in infiltration-reducing and infiltration-increasing effect for various circulation rate of intermission infiltration.
