Freezing the soil of the building foundations is one of means for sustaining the exploitation characteristics of buildings and constructions in the permafrost regions. One of factors determining the strength and stability of buildings and constructions in the cryolithozone is dynamics of temperature regime of their foundations. Thermal influence of the heated building on permafrost leads to thawing of the soil and as a consequence to its settlement. The similar dangerous cryogenic processes may create emergency situation. The mathematical model of temperature field distribution in foundation soils for geotechnical objects with pile foundation in cryolithozone is studied. Three cases are considered: a building without pile foundation, rested directly on the surface of the frozen soil; a building with pile foundation; a building on pile foundation with freezing the foundation soils using the vertical thermal stabilizers.
