The paper presents a pipe-soil coupling nonlinear model for the analysis on the vortex-induced vibration of submarine pipeline span by using finite element analysis software ANSYS,by which,the nonlinear interaction between the pipe and soil should be considered.

Vortex induced vibration of submarine pipeline span is the major factor of resonance invalidation of pipeline.

Dynamic response for free spanning submarine pipelines due to earthquake was studied by use of an underwater shaking table.

Dynamic model experiments simulating free spanning submarine pipeline were performed on a underwater shaking table.

By considering the geometrical nonlinearity, a new method for the nonlinear random vibration of a free spanning submarine pipeline is presented.
