目前国内外各领域的科技工作者对模糊数学的应用都很关注,并取得了一些效果;但在工程地质水文地质中的具体应用尚很少见。本文通过黄土类别及轻亚粘土液化判定两个实例,对模糊数学在工程地质中的应用作了探讨,不妥之处请予指正。一、模糊集的概念简述集合论是现代数学的基础。具有某种特定性质的事物的总体称为集合。集合中的每个具体的或抽象的事物本身称为集合中的元 At present, scientific and technical workers in various fields at home and abroad are very concerned about the application of fuzzy mathematics, and have achieved some results; but the specific application of hydrogeology in engineering geology is still rare. This paper discusses the application of fuzzy mathematics in engineering geology through the examples of loess classification and liquefaction evaluation of light sub-lime clay. Please correct the mistakes. I. Conceptual description of fuzzy sets Set theory is the foundation of modern mathematics. The totality of things that have a particular nature is called a set. Each concrete or abstract thing in the collection is itself called the element in the collection
