摘要
针对海底连续悬空管道的动力响应分析,文章采用ADINA有限元分析软件建立管土耦合的非线性有限元模型。讨论了双跨管道中间土体长度的变化对管跨动力响应的影响规律;与单跨管道对比分析了双跨管道中相邻跨之间的影响。通过对某海域海底悬空管线振动响应的实测,结合仿真分析结果探讨了长度较大海底悬空管线的治理方法。
For the dynamic response analysis of continuous suspended pipelines in the seabed,this paper uses adina finite element analysis software to establish a nonlinear finite element model of pipe-soil coupling.The influence of the change of soil length in the middle of the double-span pipeline on the dynamic response of the pipe span is discussed.The influence of the adjacent span in the double-span pipeline is analyzed in comparison with the single-span pipeline.According to the practical measuring for vibration response of suspended pipelines in the seabed in certain sea area,combined with simulation results,the treatments for large-scale submarine suspended pipelines are discussed.
