摘    要:通过对氯盐渍土进行溶陷试验,研究了氯盐渍土在不同含水量和含盐量条件下的溶陷变形特性,定性地分析了氯盐渍土溶陷系数与含水量、含盐量的关系。试验结果表明:氯盐渍土随着初始含水量的增大,溶陷系数下降,同时,峰值溶陷压力和峰值溶陷系数减小;在压力增加到一定值时,溶陷系数随着含盐量的增加而增大,随着含水量的增大而减小;在盐分刚开始溶解或溶解结束阶段,溶陷的敏感程度弱,而在中间阶段,溶陷的敏感性加强。

关 键 词:道路工程  溶陷  氯盐渍土  含水量  含盐量

Abstract:Based on the test results of collapsibility test of chlorine saline soil,solubilization deformation behavior were studied in different water content and salinity content conditions,and the relations between subsidence coefficient and water content and salinity content were qualitative analyzed.It was shown that subsidence coefficient of chlorine saline soil decreases with the increase of the initial water content,and peak of pressure and subsidence coefficient decreases with the increase of water content.When the pressure has increased to a certain value,the solution subsidence coefficient increases with the increase of salinity content and decreases with the increase of water content.At the beginning of dissolved salt or dissolved phase,the sensitivity of the solution subsidence was weak.In the in-termediate stage,the sensitivity of the solution subsidence was enhanced.
Keywords:road engineering  collapsibility  chlorine saline soil  water content  salinity content
