Numerical Analysis of Frost Heave and Thaw Settlement for Pipeline Buried in Frost-Susceptible Soil via Thermosiphons
Seasonal frost or permafrost soils may encounter frost heave or thaw settlement resulting from atmospheric temperature changes and/or heat emanating from the resource-carrying pipeline. Notably, these soil movements can damage the pipeline. Thus, various ground stabilization methods have been develo...

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