辽西地区风积土结构特性试验研究

在一系列室内固结试验的基础上,探讨了风积土的固结与结构特性.试验结果表明,风积土在不同状态下表现出不同的压缩性,主要反映在e-p压缩曲线上.风积土的e-lgt关系曲线与饱和黏土明显不同,主要是因为它们的细观结构和结构性不同.同时,固结系数和固结压力有较好的相关性.此外,比较阜新与其他地区的土体,说明其具有特殊的结构性.

Testing study on structural character of aeolian soil in western area of Liaoning Province

Based on a series of laboratory consolidation tests, the consolidation behavior and structural character of aeolian soil are discussed. The tests show that the aeolian soil represent different compressibilities in different variant conditions; it reflects mainly in e-p compression curve. The e-lgt curve is different obviously from saturated clay; it mainly because they have different microstructure and structural character. At the same time, there is a significant correlativity between the coefficient of consolidation and the consolidation pressure. Furthermore, it shows that the aeolian soil has special structural character by comparing the soil in Fuxin with the soil in other areas.
