Numerical simulation of pipelines’ stress-strain state in the area of longitudal landslide
S.P. Sushchev, V.I. Larionov, M.A. Kozlov, SEC ESR Bauman Moscow State Technical University; P.V. Klimov, «Intergas Central Asia» A mathematical model of underground pipeline interaction with soil in the area with longitudal landslide was developed. Differential equation of pipelines’ state was derived; corresponding algorithm and software based on methods of the finite elements, iterations and successive approximations were composed. Given example shows that area of disturbance of the stress field extends for several hundred meters to each side from landslides’ borders. Keywords: pipeline, landslide, deformation, stress, simulation, soil, shift, safety, durability, account.
