Analysis of the Danger of Lateral Exposure of the Gas Pipeline
This article presents the results of assessing the influence of the structural and technological parameters of the gas pipeline section (length, presence and height of soil above the pipe, operating pressure, temperature drop) on the value of the critical longitudinal compressive force determining its longitudinal stability at the initial rectilinear axis configuration. The article also discusses the features of the behavior of a section of a gas pipeline with a curved axis configuration during its operation and the conditions of longitudinal stability of such a section of the gas pipeline after the removal of soil along one of the lateral surfaces of the pipe, which caused its complete exposure.
