| 摘 要： | 为了解黏土中结合水的特征，对不同溶质对吸附结合水量的影响及其在以结合水充满为主的黏土中的迁移特性以及溶质的浓度对渗透性能的影响进行研究。结果表明，结合水含量受溶质的影响较大，其值大小为: 蒸馏水＞自来水＞硝酸钾＞氯化铵; 同一溶质在不同浓度下渗透速度有所不同: 氯化铵和硝酸钾的渗透速度都是随着浓度的增大而有所增大; 不同的溶质对黏土渗透性的影响不同，其渗透速度的大小为自来水＞氯化铵＞硝酸钾，说明污染质的存在使得黏土的渗透速度变小。

| Abstract: | In order to understand the characteristics of bound water in clay,the effects of different solutes on the bound water,the transfer law of different solutes in the clay filled with bound water,and the effect of solute concentration on the penetration performance are studied.The results show that solute concentration can make a significant impact on the bound water content,the value are: distilled water>running water>KNO3>NH4Cl.The permeability velocity becomes bigger with the higher concentration of KNO3 and... |
