主　　题：seabed pipeline,“J”type pipeling-lay ing method governing differential equation 

摘      要：-Considering both the seabed foundation and wave, an analytic model of J type is proposed for offshore pipeline-laying. The governing differential equation is also obtained for the pipeline on the seabed and for the suspension sections. By utilizing weighted- residual method and dual iteration technique, an approximate solution is obtained, too. In the end, calculation examples are given for analyzing the changeable relationship among the major parameters.
