摘要:对西安地区相关数据统计分析,把西安市饱和黄土、软黄土的工程性质与一般黄土进行详细对比,指出它们之间的
工程性质差异。同时重点介绍推导非饱和黄土加载体积流变模型过程以及模型的适用条件,对该模型的应用作了分析。

Abstract: Through investigating the data that correlated with the loess, the engineering behaviors of the saturated loess and the soft
loess were presented pare with the loess in Xi’an; and the differences between them are pointed out. At the same time, the
rheological model of unsaturated loess loading-volume and its applicable conditions have been described emphatically. Finally, the
application of the model is analyzed in detail..
Key words: saturated loess; soft loess; unsaturated loess; rheological model; collapsible loess
