Mechanical Analysis of Submarine Oil Pipelines Considering Overhanging ofTransition Section
並列摘要
The purpose of the study is to protect the safety of the submarine pipelines by establishing and analyzing mechanical model of the overhanging pipeline. The calculation equations of the force and deformation of the overhanging pipeline are presented in this study. In especial, the transition section is introduced to analyze the overhanging oil pipeline. The calculation equations of the moment, stress and deformation of the overhanging pipeline by considering the premise of sediment reaction are created. The software FORTRAN is used to carry out numerical simulation and the changing laws of bending moment, stress and deformation of overhanging pipeline are obtained. On the basis, the calculation equations of maximum bending moment, maximum stress and maximum deformation can be also obtained. Therefore, theoretical support for calculating submarine pipelines is provided, which has great significance for the analysis and treatment of the overhanging of submarine pipelines.
