| Abstract: | The lift up and lie down are the key operations during installation procedure of seabed pipeline.In order to simulate the lift up and lie down procedure of pipeline correctly,the geometric nonlinearity is taken into account and a material nonlinear model is proposed to deal with the pipeline contact problem as the theoretica basis.A practical example of pipeline analysis is presented to show the validity of this method. |
