Abstract

Finite element method is used for post-buckling analysis of pipeline usually. In order to study effect of interaction between pipeline and seabed, FEM of pipeline exposed on seabed is built based on ANSYS, interaction between pipeline and seabed is studied, as results show that critical buckling force is increased with lateral frictional coefficient increasing, axial frictional coefficient has little effect on critical buckling force; critical buckling force is reduced with yielding displacement increasing, which can be used for engineering design.
