中文摘要	为研究寒旱区盐渍土中盐的分布和运移特征,对青藏铁路西宁至格尔木区间具有代表性的盐渍土进行室内蒸发和冻融土柱实验,分析粘土夹层对盐分运移特征的影响。实验结果表明,土柱中的盐分在蒸发和冻融条件下都表现出较显著的聚表特征,而粘土夹层则有效阻碍和抑制了盐分的上升,这种阻碍能力随着位置由上而下依次减弱。本文的研究结果可以为寒旱区盐渍土的治理提供参考。
英文摘要	In order to study the salt distribution and migration characteristics of the saline soil in the cold and arid regions,the typical saline soil of Qinghai - Tibet railway from Xining to Golmud were analyzed through the indoor soil columns experiment under the evaporation and freezing - thawing,and the effect of clay interlayer was analyzed for understanding the the salt movement characteristics. The experimental results showed that the salts in the soil column was accumulated to the surface layer under the evaporation and freezing - thawing conditions, and the salts rise was effectively prevent and curb by clay interlayer,the ability was weaken with the position from top to bottom. This research results can provide reference for treatment saline soil of the cold and arid regions.
