Analysis of the reliability of structures during operation of gas pipelines on piles in areas of heaving soils

Abstract

The routes of the main, field, and process gas pipelines in the Arctic regions of Siberia run through territories with difficult climatic conditions. Along the route, there are areas with heaving soils, which can be used as natural bases only with the use of special anti-heaving measures, since that they are characterized by high mobility, low bearing capacity, uneven settlement and increased compressibility. This raises concerns about a decrease in the bearing capacity of permafrost soils in the territories of Taimyr, Yamal and other regions. The paper discusses various methods of the above-ground laying of pipelines on heaving soils. A pipeline construction option ensuring safer operation is proposed.
