Abstract The minimum void ratio is an index widely used to indicate the contraction characteristics and the densest state of soils. The minimum void ratio obtained by the traditional test method has been utilized to represent the density of soils irrespective of their fines content despite the restriction (FC ≤ 5%). By considering the effect of the blow count, pore water, and their primary properties, the applicability of the minimum void ratio to soils containing fines was examined with an automatic tapping machine. It was confirmed that the blow count of the traditional method is not sufficient for soils with a high fines content. Furthermore, the presence of pore water had a significant effect on the minimum void ratio of soils containing fines. The characteristics of the cyclic minimum void ratio, which indicates the minimum void ratio obtained throughout the repetition of liquefaction and drainage, were also examined.

含非塑性细粒土的最小孔隙比特性

摘要 最小孔隙比是一种广泛用于表征土体收缩特性和最密状态的指标。尽管有限制(FC ≤ 5%),但通过传统测试方法获得的最小孔隙率已被用来表示土壤的密度,而不管其细粉含量如何。通过考虑打击次数、孔隙水及其主要性质的影响,用自动攻丝机检验了最小孔隙比对含细粒土壤的适用性。经证实,对于细粒含量高的土壤,传统方法的打击计数是不够的。此外,孔隙水的存在对含细粒土壤的最小孔隙比有显着影响。循环最小空隙率的特点,
