山西潞城黄土的工程特性(英文)

Engineering properties of Lucheng Loess in Shanxi

通过对山西潞城黄土的微观结构分析研究 ,得出黄土的微观结构由两部分组成 :松散结构和密实结构。松散结构的骨架主要由粉粒构成 ,粘粒和其它细小颗粒赋着于大颗粒表面 ,起着胶结作用 ,结构内部和结构之间存在着较大的孔隙。大孔隙的存在是产生湿陷的必要条件。

The microstructure of a collapsible loess was found to be dominated by the activity of worms to a depth of 26 m.The material was divided into dense and loose areas. The loose areas contained silt clay aggregates with large voids between them.The presence of large voids permitted collapse to occur. No significant cementation has been found so far, although some of the non collapsible material contained red materials.It is suggested that the parent material differs progressively up the profile.
