description: The given work is devoted to studying defrosting of the permafrost soil in the vicinity of underground pipelines. The research set the following goals: 1. Calculation of parameters for soil; 2. Thermal problem for soil for 5 years with general depth 15 m; 3. Thermal problem for soil for 5 years with general depth 25 m; 4. Thermal problem for soil for 10 years with general depth 25 m; 5. Analysis of depth of soil thawing; 6. Analysis of sediment value; 7. Analysis of opportunities to improve the gas pumping mode. This work is based on data on soil parameters, a geometric model of the pipeline and weather condition for Yakutsk. The analysis was performed using the ANSYS software. To solve the phase change problem, the enthalpy-temperature dependences were obtained for the three types of soils: peat, gravelly sand, and low-strength granite. As a result, the thermal state of the soil was received and analyzed, and graphs of soil thawing were obtained for three problems. Based on the results of the thermal problem, graphs of soil sediment as a result of thawing are obtained. Based on the received data, the analysis of the possibility of changing the temperature regime of gas pumping in order to reduce the thickness of the thawed layer and the amount of sediment was carried out.
