Abstract

Pipeline transportation is of great significance in modern society but faces many potential safety hazards, with vibration being a significant external cause of pipeline leakage accidents. This article reviews the impact of different strain rate vibration sources (blasting vibration and mechanical vibration) on buried pipelines and the current research status of the dynamic responses of PE pipes and steel pipes. Blasting vibration has a short duration and high strain rate, which can directly damage the pipeline or indirectly cause its settlement and deformation; mechanical vibration has a wide range of sources, and the impact of impact loads and excavation loads on pipelines is complex. PE pipes have good flexibility but limitations in temperature and compressive strength, while steel pipes have a large market demand but are complexly affected by dynamic loads. Finally, the current research deficiencies are pointed out, and future research directions are proposed, including in-depth exploration of failure mechanisms, improvement of safety standards, optimization of pipe material research, strengthening of monitoring and early warning, and multidisciplinary cross-research, with the aim of enhancing the safe operation level of buried pipelines.
