| Abstract: | China's rapid urbanization intensifies third‐party excavation risks to underground gas pipelines, escalating emergency repairs and accident hazards. This study systematically evaluates the mechanical response and safety of buried steel and polyethylene (PE) gas pipelines under excavation loads through integrated numerical simulations and theoretical analysis. A 3D finite element model incorporating soil–pipeline–bucket interactions was developed using ABAQUS to simulate the dynamic response of steel and PE pipelines. Key parameters, including excavation force, bucket tooth number, burial depth, pipe diameter, wall thickness, and internal pressure, were analyzed to evaluate their sensitivity and impact on pipeline integrity. The second‐order elastic slope criterion was employed to determine the ultimate load under various excavation conditions, providing a reliable framework for safety assessment. This study provides valuable insights into the safety assessment and integrity management of buried gas pipelines subjected to third‐party excavation activities. [ABSTRACT FROM AUTHOR] |
