In this paper, we conduct an experimental study of pipeline deformation together with soil to analyze the stress-strain state of the pipeline and compare it with the results of computer simulation. The experimental setup is a box of OSB panels, which is filled with soil. A polypropylene pipe is laid in the ground, onto which strain gauges are attached, which transmit strain measurements to the computer. At the bottom of the box is a board that drives the ground with a jack. The dependence of stresses in the pipe on soil displacements is constructed first for a polypropylene pipe, then the stresses are converted to a steel pipe and compared with the results of computer simulation in Ansys. The discrepancy between the results is small, due to inaccuracy in the selection of models of soil behavior. Further refinement of mathematical models is planned.
