Thermal interference of engineering construction with permafrost ground as bottom

Abstract

Abstract.We provided laboratory results of temperature fields dynamic in permafrost ground under engineering construction which is modelling tank with oil. We wrote down non-stationary thermophysical model in the system “tank – bottom” considering mass-transfer of pore wetness. Calculated and experimental data approbation was made; close agreement of thawing halo location was shown with consideration of heat convection, associated with wetness migration in the area of thawed ground
