Abstract

In order to further study the main influence factors on the salt heaving of sulphate saline soil,the natural saline soil as subgrade filler from the sixth contract section of Kuitun-Karamay freeway was chosen to take the salt heaving laboratory tests under freezing and thawing cycles.The results show that the influences of moisture content and temperature on the salt heaving deformation of sulphate saline soil are significant.The freezing and thawing cycles tests in laboratory were employed for coarse-grained sulphate saline soil and its salt heaving property was analyzed under freezing and thawing cycles,which provide the practical experience and theoretical basis for studying the coarse-grained sulphate saline soil as subgrade filler in the future.

粗粒硫酸盐盐渍土的盐胀特性

为进一步研究硫酸盐盐渍土盐胀的主要影响因素，选取奎昆-克拉玛依高速公路第六承包段天然盐渍土作为路基填充物，进行冻融循环下盐胀室内试验。结果表明:含水率和温度对硫酸盐盐渍土的盐胀变形影响显著。采用室内冻融循环试验对粗粒硫酸盐盐渍土进行了冻融循环试验，分析了其在冻融循环作用下的盐胀特性，为今后研究粗粒硫酸盐盐渍土作为路基填料提供了实践经验和理论依据。
