Study of the Effect of Cutting Frozen Soils on the Supports of Above-Ground Trunk Pipelines

The transportation of oil and gas in Russia’s northern Arctic regions has seen significant growth recent years. However, the presence permafrost these areas can cause malfunctions main pipelines due to soil frost heaving. operational also often suffer from various defects their body surface. To mitigate issues, above-ground trunkline supports are utilized protect cryogenic processes. Nevertheless, subjected ground loads caused by heaving, which poses a threat pipeline’s integrity environment. In response challenges, this study presents design for pipeline support maintain stability face displacement unequal frost-heaving forces. A numerical model was created evaluate fracture frozen rock resulting stresses structure. input data includes coefficients that describe soil’s state during process proposed support’s parameters. experimental results showed be effective protecting paper provides studies on depending type temperature. This promises increase both safety trunk technological efficiency.
