粗粒硫酸盐渍土盐胀特性
Characteristics of Salt Heaving for Coarse-Grained Sulphate Saline Soil
摘要
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.关键词
