Abstract

The buried steel pipeline is confined by the surrounding soil, and the deformation is often too large and buckling occurs due to the change of the environment, which becomes one of the difficult problems in the integrity management of buried steel pipeline. At present, most of the studies on buried pipeline buckling accidents focus on a single buckling failure analysis case and study the buckling deformation mode of pipelines under a specific environment, but lack a summary study on buckling failure mode, which leads to a lot of repetitive work in practical engineering and reduces the efficiency of pipeline integrity management. Based on relevant literature research and analysis of buckling failure cases, this paper calculates the causes of pipeline buckling failure, summarizes the buckling factors in each case, and summarizes the buckling failure modes in practical projects. According to the analysis of existing failure cases, there are four buckling modes of steel pipe, which are asymmetric buckling, symmetrical buckling, concave buckling and full circle buckling. Each buckling mode has different load forms, and the causes of buckling should be analyzed according to different service environments in practical engineering. The research results of this paper provide a theoretical basis for buckling failure analysis in practical engineering.
