    EXPERIMENTAL STUDY AND ANALYSIS OF CHARATERISTICS OF SALINE SOIL OF TURPAN BASIN IN XINJIANG

    • 摘要: 为深入研究新疆试车场高速试验环道地基盐渍土特性,文中通过399组易溶盐试验揭示了盐渍土在平面和竖向的分布特征和规律,综合运用双线法试验和室内溶陷性试验进行盐溶特性研究,通过盐胀性试验得到不同含盐量试样的盐胀规律,研究结果表明:场地盐渍土具有含盐类型变化大、盐渍化程度高、盐分表聚性强等特点;自然地面以下2 m深度范围内的地基溶陷等级为弱溶陷Ⅰ级;通过施加荷载和降低硫酸盐含量能够抑制盐胀作用。

       

      Abstract: In order to study characteristics of saline soil in high speed test ring road of Xinjiang test track, 399 experiments were carried out to reveal the plane and vertical distribution laws of saline soil, double-line method and collapsibility test were carried out to study the melt sinking characteristic, salt-heaving tests were carried out to get the salt-heaving laws of soil samples which have different salt content. The results show that the saline soil has variety, high salinity and even surface assembled, grade of foundation dissolution within 2m below the natural terrain is judged as the first level of weak collapsibility, and the salt-heaving can be restricted by increase of load and decrease of sulphate content.
