The article presents an algorithm for analyzing the stability level of main gas pipelines located in irrigated non-cohesive soils. The algorithm serves to estimate the longitudinal stability for uneven placement of anchor devices along the pipeline. Multivariate algorithms of automated calculations, for their part, provide a methodological basis and justify the selection of basic requirements for technological parameters. The latter would provide the anchors with their required bearing capacity for arbitrary distribution along the length of the pipeline. The anchor devices, the critique relates, enhance the stability level. Moreover, they depend on elements of the ’fuzzy set’ theory, mathematical models and other concepts that influence the quality of pipeline sectional construction and installation work, as well as its operational reliability. The study has determined that the quality of the anchor installation has a significant influence on the transverse load; it also regulates the total number of anchors. Finally, the paper has indicated that the anchor devices closest to the pipeline’s midsection are able to provide it with the maximum level of sustainability.
Key words: main gas pipeline,anchor devices,non-cohesive soils,retention capacity,longitudinal and transverse load.
