The paper describes a study of thermal interaction between underground gas pipeline and surrounding permafrost and seasonally thawing soil. A forecast of the soil’s thermal mode depending on thermal insulation on the pipeline is made by means of numerical simulation with finite elements method. The analysis accounts for air temperature, thermal radiation balance of the ground surface, wind speed and snow thickness.
