温度对土体微孔隙特征影响的试验研究
摘要:采用烘干法和冻干法分别对深圳土和重塑膨润土进行干燥制样,利用压汞试验得到的累积进汞量曲线,对土体进行了孔隙尺度划分,分析了土体采用不同温度烘干和冻干法干燥制样后孔隙分布存在的差异性,得出了制备压汞试验用土样时,冻干法优于烘干法这一结论。
Abstract:The Shenzhen soil and remolded bentonite was prepared after drying with drying method and freeze dry method, with the cumulative intrusion curve obtained form mercury intrusion test, gave the division of pore scale for soil according to the test result. The difference of soil prepared by drying method in different temperature and freeze dry method was analyzed, and draw the conclusion that when drying for soil sample using in mercury intrusion test, the freeze dry method was better than drying method.
