Numerical Simulation on Mechanical Response of Buried Pipeline under Uneven Settlement

Abstract

Abstract-Uneven settlement will cause the buried pipeline deformed, even crack. A 3-D finite element model for buried pipeline was established by ADINA to investigate the deformation of pipe under uneven settlement. Furthermore, the effects of some key factors on mechanical response of buried pipeline were analyzed. Results indicate that the maximum axial stress increases with the decreases of diameter and wall thickness, the increases of the soil stiffness and buried depth.
