MODELING OF THE DEFORMED STATE OF UNDERGROUND MAIN PIPELINES MADE OF PE 80

The development of underground layers of minerals induces significant deformations in the subsurface soil layer, thus causing surface subsidence troughs. The displacement zones can reach several kilometers and significantly affect the strained state of underground pipelines. In this regard, the assessment of the strained state of such pipelines is a technically difficult task. Long pipelines experience a complex strained state due to large diameters, high pressure, as well as the variability of the properties of the pipe material and soil. Based on the results of finite element simulation, an assessment of the deformations of the soil mass, which lead to a loss of the bearing capacity of various underground main pipelines, is made. Calculations are performed for a number of basic structural materials and operating conditions.
