The aim of the work is the mathematical modeling of the interaction of the elements of the «steel corrugated pipe-base-backfill» system in two different software packages, analysis and evaluation of the stress-strain state of this system based on FEM. To simulate a two-dimensional model, the PC Lira and the PC GenIDE32 were used. The features of the calculation are the accepted soil model and the consideration of the sequence of construction of the steel corrugated pipe (SCP) and the soil backfill. For comparison, the calculations were carried out according to three schemes in each PC: 1) flexible model of soil without taking into account the sequence of construction, 2) elastic-plastic soil without taking into account the sequence of construction, 3) elastic-plastic soil taking into account the sequence of construction.
