安徽膨胀土的微观结构与其工程性质的关系研究

<TITLE>STUDY ON THE RELATION BETWEEN MICROSTRUCTURE OF EXPANSIVE SOIL AND ITS ENGINEERING PROPERTY,ANHUI

膨胀土在安徽省内分布较广,文章通过对安徽省内部分典型分布区取得的土样,运用X射线衍射、偏光显微镜、扫描电镜(SEM)、化学全分析等实验手段,得出了土样的相关参数,研究了膨胀土的微观结构,分析了微观结构与其工程性质之间的关系。膨胀土微结构的定性研究,为安徽省内工程建设提供必要的数据,同时也为深层次的定量研究奠定一定的基础。

Expansive soil is widespread in Anhui Province.This paper analysed soil samples collected from some typical areas using X-ray diffraction,polarizing microscope,SEM and complete chemical analysis,obtained relevant parameters of soil samples,studied microstructure of expansive soil and concluded the relation of the microstructure and its engineering property.Qualitative study of the microstructure provides required data for engineering construction in the province and also lays a basis for further quantitative study.
