模糊评判法在膨胀土识别分类中的应用

摘要

运用模糊数学的方法对膨胀土的膨胀力、自由膨胀率、液限、塑性指数4项指标进行综合评价，建立模糊识别分类方法，简单介绍了模糊数学的基本知识，并对膨胀土胀缩等级模糊评判在工程中的具体应用作了阐述，经实践证明，此方法具有一定推广价值。%This paper comprehensively evaluates the expansivity, free expansivity, liquid limit, and plastic indicator of expansive soil by using fuzzy mathematics, establishes fuzzy classification and identification method, and briefly introduces the basic knowledge of fuzzy mathematics, and describes the specific application of expansion and shrinkage grade fuzzy evaluation of expansive soil in engineering. Practice proves that this method is worth pl~omoting.
