| 摘 要： | 本文就笔者搜集到的几种不同的膨胀土样进行了基本特性研究,如物质组成、物理化学性质、微观结构等。特别是对影响膨胀土胀缩特性的某些因素作了较深入的研究。对表征膨胀土胀缩特性的某些因素,如风干(或吸着)含水量、单位干土重的自由膨胀体积以及膨胀土分类图首次法等被用来研讨膨胀土,并在文中作了初步的讨论。

| Abstract: | The basic properties of some expansive soils such as composition, physic-chemical properties and microstructure etc. are studied in this paper. Especially, the factors influencing swell and contraction properties of expansive soil are thoroughly investigated. Several characterizing factors for swell and contraction properties (such as air-dry moisture we and free swell volume per unit dry weight VPS) and a new method for classification are used for the first time in the study of expansive soil. |
