摘要:
针对几种常见的缺陷形式,利用有限元软件进行屈曲稳定性分析,并对海底管道整体腐蚀和局部腐蚀两类缺陷进行了仿真计算,拟合得到了较为简单的含缺陷海底管道临界载荷的近似计算公式,可供工程设计人员进行相关设计和评估时参考使用,同时也为制定新的含缺陷海底管道屈曲稳定性设计规范提供了参考依据.
Abstract:
This paper is to propose some approximate formulas for the major imperfections of the pipelines by FEM numerical simulations. Two cases are simulated,i.e.,the pipeline segment is totally and locally corroded with the wall thickness reduced in a way described as relatively simple formulas of critical loads of subsea pipeline with imperfections. These formulas are of practical value in engineering design,and can be referenced by future codes and rules for subsea pipeline buckling stability evaluations.
