Coupled Interaction Mechanism Between Shallow-buried Gas Pipelines and Soil During Mining

Abstract

Abstract: Underground coal mining can potentially induce deformation and destruction of shallow-buried gas pipelines in subsidence areas. Thus, this study analyzed the interactions between a pipeline and soil during mining activities and divided them into three types based on the fundamental characteristics of pipeline-soil interaction. These include collaborative pipeline-soil deformation, hidden pipeline-soil suspension, and apparent pipeline suspension. Depending on the mechanical characteristics of the buried pipeline in each type of interaction, an elastic foundation beam model, uniform loading elastic beam model, and twoway bending elastic beam model were used to analyze the mechanical behaviors of pipelines in a subsidence-free area, pipelines under collaborative deformation in a subsidence area, and pipelines suspended in a subsidence area, respectively. Based on this analysis, a segmented elastic beam mechanical model was developed for buried pipelines of each type. Combining the model with the corresponding boundary conditions, this study further analyzed the ultimate conditions of pipeline-soil interaction and the critical criterion for buried pipelines of each type. Finally, an analytical method for investigating the mechanism of interaction between shallow-buried gas pipelines and soil during mining was established.

Key words: buried pipeline, mining subsidence, the segmented elastic beam, coordinated deformation, suspended stage
