Analysis of Coarse Saline Soil Salt Expansion Characteristics with Different Freeze-Thaw Cycle

Abstract:

Salt expansion deformation of the saline soil is a common form of the roadbed disease in Saline Soil Area. Salt expansion of saline soil refers to volume expansion by the impact of periodic climate changes in nature. Particle distribution characteristics, compaction characteristics, salt composition and salinity and so on are studied to evaluate the basic engineering properties of saline soil in the location of the project. Seven freeze-thaw cycles test and (no) load single-cooling test are designed to clarify the relation between salt expansion and temperature changes, moisture content, overburden pressure. The results provide design and construction experiences for high-grade highway projects in natural coarse saline soil area.
