Thermal characteristics of salty soil are researched by TG-DSC technique. The results show that soluble salts have great influence on thermal characteristics of salty soil; water content gets higher, phenomena gets acuter. Freezing force depends on water content and freezing temperature; the more water content or the less temperature is, the more intensive of freezing force is.
