The article considers the features of designing the bases and foundations of buildings and structures in the permafrost zone. It is shown that the developing global warming requires, in the case of using principle I, to provide for the cooling of the base with the help of heat stabilizers. It is recommended to use horizontal heat stabilizers, which contribute to the formation of a slab of frozen soil at the base, making it possible, in some cases, to abandon the use of piles. When using a ventilated underground, it is proposed to use backup heat stabilizers, which can start operating as the soil temperature rises. In the case of using principle II, it is possible to stabilize plastic frozen soils by injection of cement grout in hydraulic fracturing mode.
