黄土湿陷性机理及其影响因素分析

Analysis of the Collapsible Mechanism and Effect Factors of Loess

黄土作为一种特殊土,广泛分布于世界各地,各地区黄土的工程地质性质在区域上存在一定的变化规律。这种变化规律和黄土在大区域上的变化规律是一致的,本文从黄土的微结构方面阐述了黄土湿陷产生的机理,并详细探讨了含水量、孔隙比、物质组成,微结构等因素对黄土湿陷的影响。

Loess is a special soil, is widely distributed in all parts of the world, engineering geological nature of the loess had the change law in certain areas. This change law samed with the law which changed in large region. This paper analyzed the collapsible mechanism from the micro -structure of loess, and discussed the effect factors of loess collapsible, such as the water content, porosity, material composition, microstructure, and so on.
