The Analysis of Pipeline’s Penetration Laid on the Elastic-Plastic Seabed Based on the ABAQUS Software

Abstract:

The pipeline’s stability is the key problem of submarine pipeline’s design. In order to supply the theory basis for the pipeline’s design, the ABAQUS software has been adopted to analyze the pipe/soil system. The Ramberg-Osgood model has been adopted to simulate the seabed; the contact pair also adopted to simulate the pipe/soil system, the dynamic boundary contact problem of pipe embedded into the seabed has been analyzed. The computation has been operated according to change pipe’s subweight, environment load, pipe’s diameter, yielding stress and so on. The computation results have shown that these parameters have effects on the pipe’s penetration.
