摘要
通过对新疆焉耆地区和硕至库尔勒高速公路沿线天然盐渍土的室内基本性质试验分析,选取粉土、粘土类天然盐渍土在开放系统中进行反复冻融循环条件下的试验研究,从土类及盐性角度研究得出氯盐渍土的盐胀规律。通过对氯盐渍土进行溶陷试验,研究氯盐渍土在不同含水量和含盐量条件下的溶陷变形特性,并定性分析氯盐渍土溶陷系数与含水量、含盐量的关系,可供工程人员参考。
Through the indoor test study on the basic property of natural saline soil along HoxudKorla Expressway in Yanqi District of Xinjiang Uygur Autonomous Region,silt and clay saline soil are selected to be tested at the freezing and thawing cycle condition in open system.The law of salt heaving is summed up from the view of soil and salt.Through the melt sinking test,the melt sinking and deformation characteristics of chlorine saline soil with different moisture content and salt content are studied,the relation ship between melt sinking coefficient and moisture content or salt content are analyzed qualitatively,which can be consulted by engineers.
