    Abstract. Seasonally freezing and permafrost soils are spread on the territory of any countries. Many works, both Russian and foreign researchers, have been devoted to their study. Some of them consider the processes of heat exchange in soils around cooling devices or thermal barriers. Analyzing these publications, as well as domestic regulatory documents, it is possible to note the influence of foundations on the temperature distribution in the surrounding soil massif. At the same time, literary sources and regulatory documents do not fully reflect this whole process, since the type of foundation, thermal properties of its materials and dimensions in the case of freezing are not taken into account. Also, a set of factors affecting the size of the funnel formed at the foundation from frozen or thawed soil remains not fully understood. For a more detailed study of this process, this study was conducted. Having identified eight factors presumably influencing the formation and size of the specified funnel, many problems were solved sequentially by the finite difference method, in each of which only one factor changed. The results demonstrated the influence of foundations on soil temperature. The main factors influencing the size of the funnel around the foundation were identified. Dependences of funnel sizes on different factors have been established. Based on them, recommendations are given for the design of foundations in conditions of seasonal freezing and thawing of soils.
