Аннотация: In connection with degradation of permafrost soils, the issue of designing and building foundations is acutely raised, taking into account the possible thawing of the soil at the base of structures. A spatial foundation platform is less sensitive to deformations of the foundation soil due to the integral work of the structure, compared to other foundations. For this and a number of other reasons, the use of the platform is promising. As the main structural material in spatial foundation platforms, it is advisable to use engineering wood, because of its advantages in comparison with reinforced concrete and metal. The article presents some results of calculations of the foundation platform of the folded type. The COMSOL Multiphysics software package simulates the process of thermal degradation of the soil under the foundation platform caused by an increase in air temperature. As a result, the soil warming zone was established, which is necessary for the design of the foundation platform taking into account changing boundary conditions. Preliminary conclusions are made about the influence of the degradation of the frozen base on the stress-strain state and the structure of the foundation platform of the folded type. © Published under licence by IOP Publishing Ltd.
