摘要

The results of numerical simulations of some selected states of loading the pipelines within the non-linear range, with account taken of large displacements and deformations, are described in this paper. Numerical analyses resulted in sizes of deformations, strains and stresses, which further on were used to conduct comparative analysis with results effected by tests carried out on a testing stand under laboratory conditions. At points where the pipeline is supported with pipe bearers, various kinds of dents, folds, ovalisations of the pipeline's cross-section may occur so that results of numerical simulations enable evaluation of deformation sizes in a real pipeline structure.
