【 摘 要 】

The authors of the article developed a finite-element model of a soil with a thermal stabilizer that takes into account the thermal effect from the environment, as well as the temperature of atmospheric air, wind speed, magnitude of the heat flux from solar radiation, albedo of the active surface, magnitude of the heat flux in the infrared, thermal conductivity of the snow cover, thermal conductivity and heat capacity of the soil, which makes it possible to calculate the haloes of freezing the soil. The results of a numerical experiment conducted using the COMSOL Multiphysics software complex showed that using the developed design of the thermal stabilizer allows increasing the zone of soil freezing around the bottom of the cooling device.
