When studying freezing, permafrost and thawing soils, it is absolutely necessary to develop models of processes occurring in soils and their mathematical description as a basis. This will make it possible to perform a calculated assessment of the "thawing foundation - structure" system during the entire lifetime of the object, which will make it possible to design it correctly. The article considers a soil model that allows us to consider the process of degradation of permafrost soils of the base of the railway roadbed in the zone of passage of construction equipment.
