Abstract
This paper presents the developed analytical model of the functioning of the system of temperature stabilization of soils of the "HET" type, based on the integral method. The paper presents the solutions of numerical and analytical models for temperature stabilization systems of soils of the "HET" type with different lengths of the evaporating part, as well as for the Arctic cities with different climates - Salekhard, Varandey, Igarka. By comparing the results obtained within the framework of numerical and analytical solutions, it has been concluded that the developed analytical model can be used for an express assessment of the functioning of the system of temperature stabilization of soils of the "HET" type for various design solutions and climatic characteristics.
