Numerical Analysis of Frost Heave and Thaw Settlement for Pipeline Buried in Frost-Susceptible Soil via Thermosiphons

Seasonal frost or permafrost soils may encounter heave thaw settlement resulting from atmospheric temperature changes and/or heat emanating the resource-carrying pipeline. Notably, these soil movements can damage Thus, various ground stabilization methods have been developed to prevent onset of phenomena in frost-susceptible soils, and application thermosiphons is a representative method. Recently, numerical analysis method called thermosiphon model for pipeline has developed; however, study only focused on ability reduce using thermosiphon. Therefore, here, was conducted determine performance buried according by applying via ABAQUS. For novel analysis, two scenarios are established: settlement. each scenario, behaviors compared four cases, distinguished arrangement applied. The results indicate that thermosiphons, frost-heave thaw-settlement verifiably reduced up 62% 82%, respectively, when no
