Abstract : Frozen soils, particularly the dispersed ones, are extremely susceptible to external influences. The slightest changes in the value of their negative temperature or chemical composition of water, variations in external pressure, etc. are reflected significantly on the frozen soils' properties. The report discusses the following topics: Effect of freezing on certain physical and physico-mechanical properties of soils; Effect of thawing on variation in frozen soils' properties; Variation in physico-mechanical properties of soils as a result of a freeze-thaw cycle.
