Development of Methodology for Main Pipelines Linear Section Stress-Strain State Changes Assessment

摘要

The linear section of main oil and gas pipelines, which are potentially the most dangerous type of pipeline networks, was selected as the object of investigation. A technique for assessing the stress-strain state of the pipeline was developed. Underground pipeline deformation process was mathematically modeled according to the set of points displacement. The process of the underground pipeline points position determination process, estimation of the interpolation accuracy of the underground pipeline spatial position, interpolation step and smoothing parameters determination were described.
