Abstract:The applicability of the soil spring calculation model given in China’s standard SY/T 7403 “Code for strain-based design of oil & gas transmission pipelines” and GB/T 50470 “Seismic technical code for oil and gas transmission pipeline engineering” to large-diameter pipelines is not clear. In this paper, the soil spring calculation formulas recommended in the two standards are analyzed, and the corresponding finite element numerical simulation models are established. The applicability of the lateral and ver… Show more
