| 摘要: |
| 对3个典型黄土地区的原状黄土样在不同湿度状态下的湿陷特性进行了研究。探讨了含水率，干密度，压力对黄土湿陷性的影响规律，着重从结构性的角度解释了不同地区间黄土湿陷特性的影响。基于不同地区间黄土湿陷特性的差异这一事实，提出了黄土潜在湿陷率的概念。结果表明，这一概念可用于对黄土湿陷性的分析，并能较好地反映不同黄土种类的结构特性。 |

| Regional collapse characteristics of intact loess and its rate of potential collapse |
|
|
| Abstract: |
| In this paper,collapse characteristics of intact loess from three typical loess areas under different moisture condition are studied,and the principles of loess collapsibility influenced by water content,dry density as well as pressure and behaviors of these in different loess are approached respectively.Base on the collapsibility difference existing in different loess area,a concept of rate of potential collapse is presented,and the test results show that it can be used to analyses the loess collapsibility and reflect the structure characteristics for different kinds of loess preferably. |
| Key words: intact loess collapse characteristics rate of potential collapse |
