In article present the developed methodology will allow monitoring pipeline displacements under changes in operating conditions, as well as simulating unfavorable processes (thawing of soil, formation of taliks, violation of thermal insulation). The planning of the experiment was carried out to obtain the calculated mechanical characteristics of the soil, depending on the temperature and humidity, used to calculate the stress-strain state of the pipeline. A mathematical computer model has been developed to determine the radius and temperature field of the thawing halo around the pipeline. A template for displaying experimental data for their use in the finite element analysis of pipeline displacements during soil thawing is presented.
