The article presents data on the planned and high-altitude position of the pipeline for the period of November 2024 – April 2025. The measurements were conducted in April, when the pipeline is in frozen soil, and in November, when the soil around the pipeline is thawed. It has been confirmed that the processes of freezing and thawing of the soil around the main gas pipeline on the main terrace of the floodplain zone and on the channel are uneven. The changes in the high-altitude position of the pipeline can reach up to 2.0 m.
