Modeling the Impact of Soil on the Stress-Strain State of a Linear Section of a Pipeline with Cold Bend Bends Using ASYS Tools

Abstract

he purpose of the article is to consider a local problem associated with deviations from the norm of bends resulting from uneven subsidence of soil under an underground linear section of a pipeline with a cold bend outlet. Modeling and calculation of the linear section of the pipeline was carried out in the ANSYS software environment, which made it possible to identify the maximum possible length of the soil failure, at which the structure will suffer irreversible deformations due to climatic conditions and other natural factors. The data obtained will allow assessing the risks during the laying and operation of the pipeline.
