摘要：
The results of assessing the stress-strain state of the surveyed main gas pipelines in the area of violations of the shape of cross sections (buckling) are presented. The results are based on actual measurements of buckling and its shape, as well as on the application of thin shell theory methods to estimate the initial strains and incremental strains during internal pressure loading. Criteria for the performance of pipelines are presented, taking into account defects such as buckling.
