Abstract

Saline soil water-salt movement results to subgrade diseases like collapsibility, salt expansion and secondary salinization in coastal areas with saline shallow water table. Column tests were carried out to study the regularity of coastal saline soil water-salt movement. Results show that coastal saline soil with a higher level of groundwater salinity has a higher capillary rising height. And both water content and salt content are higher either. Since coastal saline soil is fat clay, the increase of compaction degree may decrease capillary intense rising height, together with its water content and salt content. The findings suggest that controlling measures of coastal saline soil water-salt movement should be considered from desalination, water controlling and structural strengthening.
