| 摘 要： | 本文总结了目前关于湿陷性黄土湿陷机理的诸观点,对典型的湿陷性黄土地区的公路路基黄土进行了大量野外取样并进行了室内湿陷性试验,通过对试验结果的回归分析揭示了湿陷性与含水量、孔隙比、塑性指数的定量关系;并通过对切取的sem电镜照片进行分析,从微观角度对黄土微观结构特征与湿陷性之间的关系进行了有益的探讨。

| Abstract: | In this paper,various points on the collapse mechanics of loess are generalized.After that,the authors carried various tests on loess samples collected from highway subgrade in the typical collapsing loess areas,based on which the regression equation between collapsing coefficient and relative physical data is figured out.Through electron micrograph,the inner relationship between microstructure of loess grains and collapsibility is analyzed. |
