Abstract

In the alluvial plain area of the Ush Talar River, there is a widespread distribution of fine saline soils. Due to the special properties of fine saline soils, they are highly prone to issues such as salt heaving, thaw settlement, and mud pumping, which often cause harm to engineering structures. Water-salt migration is a key process that leads to changes in the physical and chemical properties of saline soils and is a major cause of the damage that occurs in these soils. To analyze the impact of different control measures on water-salt migration, this study conducted water-salt migration column experiments under different water-isolation conditions. The results show that the rate of increase in water-salt content in the middle of the treated soil columns was significantly lower than that in the control group. During the experimental period, the highest salt content in the middle of the control group soil column was 1169 mg/L, and the water content was 11.3%. The use of aeolian sand replacement and the installation of a “two fabrics and one membrane” isolation layer reduced the salt content by 47.7% and 70.4%, and the water content by 33.6% and 48.7%, respectively. These results indicate that both isolation conditions effectively inhibit water-salt migration in fine saline soils, with the isolation layer proving to be more effective. This study provides reference and theoretical data support for practical engineering and soil salinization prevention projects.
