The article considers the behavior of pile foundations of buildings constructed on permafrost soils with the preservation of the frozen state, depending on the methods of cooling the base: surface cooling using a cold underfloor space and deep cooling using the seasonal cooling devices (SCD) located along the perimeter of the building together with effective thermal insulation of the base. It is shown that in the first case, during longterm operation of piles, periodic seasonal fluctuations in temperature and stresses in the upper layers of the base can lead to a significant decrease in the bearing capacity. In the second case, the amplitude of temperature fluctuations in the frozen base is significantly reduced. Due to the stabilization of the annual temperature mode, not only the reliability and bearing capacity of pile foundations increase, but also the use of a foundation slab resting on frozen soils becomes possible.

本文考虑了在永久冻土上建造并保持冷冻状态的建筑物的桩基础的性能，具体取决于冷却基座的方法：使用低温地板空间进行表面冷却，以及使用季节性冷却装置（SCD）进行深层冷却沿着建筑物的周界以及有效的底座隔热层。结果表明，在第一种情况下，在长期使用桩的过程中，基层上层的温度和应力的周期性季节性波动会导致承重能力的显着下降。在第二种情况下，冻结基部中温度波动的幅度显着降低。由于年度温度模式的稳定，不仅增加了桩基的可靠性和承载力，
