Technical Article---Peer-Reviewed


In order to study the stress-strain response of a buried pipeline with internal pressure under the ground explosive, a numerical calculation model of the buried pipeline with internal pressure was established. The dynamic process of the buried pipeline was simulated after the explosion on the ground. Effects of internal pressure, magnitude of TNT, wall thickness, and buried depth on the stress-strain of pipeline were studied. The results showed that the region of high stress and plastic strain presented to the upper pipeline and extended toward axial direction, and then extended toward circumferential direction under the ground explosion. With the increasing of internal pressure, the high-stress zone fades away, the plastic strain zone and deformation of pipeline decrease. The stress and deformation of buried pipeline increase with the magnitude of TNT increases, but they decrease with the increasing of buried depth and wall thickness. Those results can provide theoretical basis and reference for pipe laying of oil-gas pipeline, safety evaluation, and maintenance, etc.
