Abstract.

This article examines the issue of numerical modeling of the soil freezing-thaw process for projection of thermal stabilization system of soil building foundations in the cryolithozone of the Sakha Republic (Yakutia). The goal of this work consists in studying the process of formation of the temperature field of the massif of the soils under the effect of thermal stabilizers. Research is conducted on the process of formation of ice wall as the result of thermal exchange of the soil with the thermal stabilizers and external cool air during clearing of the snow cover from the construction site. The main conclusions of the conducted research include the need for development of mathematical models that would account for the mass exchange processes in the zones of effect of the thermal stabilizers with consideration of the conditions of formation of the cryogenic textures in the process of forced freezing of the soils. There is also a need for mathematical explanation of the phenomena of condensation and evaporation of Freon taking place inside the thermal stabilizers.

Keywords: temperature field, heat exchange, The Stefan problem, mathematical model, termal stabilizers, soils, cryolithozone, freezing - thawing, structures, permafrost
