摘要
首先从黄土的结构特征认识出发探讨了黄土湿陷性的内在因素;其次通过试验数据分析找出对黄土湿陷性影响最大的因素,并进而研究了黄土湿陷发生的作用机制。由此从内因和外因两方面较好地阐述了黄土湿陷性的实质及其发生机制。
In this paper, the internals factors of loess water collapse are discussed from the microstructure point of view. Then, based on laboratory test, the most determinant factors on loess water collapse are found and the mechanism of water collapse of loess is revealed based on the known facts and theories. Through study from the two aspects, the problem of water collapse of loess and its nature are better explained.
