PHASE TRANSITION ANALYSIS IN FREEZING MOIST SOILS CARRIED OUT ON THE BASIS OF PHASE TRANSITIONS CHARACTERISTIC TO THE DIFFERENT TYPES OF SOIL WATER

摘要

The analysis of the mass exchange between the nonfreezing bound and nonfreezing transient water types, as well as that between the nonfreezing transient water and ice in frozen soils has been done. The comparison between results obtained with radiometric and calorimetric methods made it possible to to explain apparent heat capacity behavior during a freezing event using the observed phenomena of phase transition in bound, transient, and capillary soil water types.
