Description
Summary:This article explains the changes of the main gas pipeline geometrical shape, i.e. the deviation of its position from the project one, as one of the important factors affecting the operating safety of underground main pipelines. In the study of the processes occurring at interaction between main gas pipeline and foundation soil, a rod model, fixed on one side, with the load applied to, it was examined. Action of elastic foundation across the pipeline is modeled with spring substrate that resists cross motion. As a result, the effect of soil impact on the vibration frequency of the pipe wall, appearing at the stage, preceding its deviation from the design position, was determined. Detection the frequency of these vibrations can make it possible to forecast pipe bending not at the stage of growth but at the stage preceding its appearance.
