碱溶液对GMZ膨润土膨胀性和渗透性的影响 陈宝,张会新,陈萍 (同济大学 岩土及地下工程教育部重点实验室,上海,200092) 摘要:利用适用于碱性溶液入渗的膨胀渗透仪,对不同初始干密度的高压实高庙子(GMZ)膨润土进行膨胀,渗透试验,试验中用NaOH溶液模拟碱性孔隙水.试验结果表明:在碱溶液入渗作用下,各试样的膨胀力均呈现双峰变化形态；相同初始干密度试样的膨胀力随入渗碱溶液浓度的增大而减小,渗透系数则随着溶液浓度的增大而增大；碱溶液浓度相同时,试样的膨胀力随初始干密度的增大而增大,渗透系数随干密度的增大而减小；碱性孔隙水的长期入渗会减小高压实GMZ膨润土的膨胀性,提高其渗透性,最终降低膨润土的缓冲性能. 关键词:膨润土；膨胀力；渗透；高碱性；干密度 中图分类号:P619.25+5 ......
the soil-water retention curves (SWRCs) of highly-compacted confined/unconfined Gaomiaozi (GMZ) bentonite at 20, 40 and 80 ℃, respectively. The effect of temperature on the soil-water characteristics of the highly-compacted GMZ bentonite was analyzed. The results show that the water retention capacity of the highly-compacted GMZ bentonite decreases as the temperature increases under unconfined......
