土体的物理性质与力学性状之间存在一定的联系,研究不同混合比例的混合土的物理性状变化,对于快速测定混合土体的力学参数有很大的帮助。通过对两种原始黏土及人工配制的五种不同混合比例的混合土的物理性质进行研究,探讨混合土的颗粒粒径分布、土粒密度、液限以及塑性指数随混合比例的变化规律。研究结果表明:原始土的性质对混合土体的基本物理性质产生重要的影响。混合土的颗粒粒径分布和土粒密度按混合比例成比例的发生变化,随着混合土中膨润土百分含量的增加,其黏粒含量线性增加,粉粒含量线性减小,砂粒含量线性减小;混合土的液限与塑性指数的变化规律一致,以非线性的方式随着混合土混合比例的变化而变化,其中在混合土中含有膨润土的情况下,这种变化趋势更加明显。
It is well known that there is a certain relationship between the physical properties and mechanical properties of soils, so it is of great significance to study the physical properties of mixed clays with different mixing ratios for quickly determining the mechanical parameters of mixed clays. Research on the physical properties of two kinds of original clays and five kinds of mixed clays with different mixing ratios was carried out, the change laws of the particle size distribution, soil density, liquid limit and plasticity index of mixed clays with mixing ratios were revealed. The results show that the physical properties of the two original clays have an important influence on the physical properties of the mixed clays. The particle size distribution and soil particle density of the mixed clays change in proportion to the mixing ratios. With the increase of the percentage of bentonite in mixed clays, the clay content increases linearly, the stilt content decreases linearly, and the sand content decreases linearly. The change of liquid limit of mixed clays is consistent with plasticity index. They change in a non-linear manner with the mixing ratios of the mixed clays, which is more obvious when the mixed clays contain bentonite.
