本文着重讨论了砂土下限的两个建议:大于75μm的粒组超过50%和粘粒含量M_C=5%;指出在的工程分类中,粘粒含量不宜作为大类的界限,并认为砂土下限应采用75μm的方案。
This article focuses on two proposals for the lower limit of sand: more than 50% for grain groups larger than 75 μm and M_C=5% for clay content; it is pointed out that in the engineering classification, the clay content should not be taken as the boundary of large categories and sand is considered The lower limit should be 75μm.
