【摘要】 为了研究土体微观结构与其土水特性等水力学指标之间的关系,基于常规固结实验、土水特征曲线实验和扫描电镜观察,获得了不同密实度试样的微结构参数、排/吸水差异等宏微观指标。在此基础上,给出了平面孔隙比与土水特性指标之间的关系。研究表明,土样的排水能力和吸水能力获得最大值时,对应的平面孔隙比是不同的。更多还原

【Abstract】 In order to investigate the relationship between the microstructure and soil-water characteristics of remolded clay with different densities,the conventional consolidation test,the soil-water characteristic curve test and the scanning electron microscope observation were carried out,and micro and macro parameters such as the microstructure parameters and the drainage and absorption parameters of soil of different densities were determined.And the relationship between plane void ratio and soil-water characteristics was obtained.The results indicated that the plane void ratio of soil was different when its drainage or absorption capacity reached the maximum.更多还原
