摘要
海底管道在多种因素作用下会出现淘空现象而产生悬空管段。该文针对埕岛油田的海底悬空管道建立了有限元模型和土壤的温克尔模型,并将两者耦合成整体结构的有限元模型,来模拟管跨振动和土壤的液化,寻找海底悬空管道振动的特点和规律,分析特定条件下管道悬空的动力学响应,对合理设计海底管道和指导现役管道的维修提供了较为科学、可靠的依据。
scouring of the submarine pipelines leads to hanging on account of many factors. The finite element analysis has been made of the suspended submarine pipelines of Chengdao oil field. The pipeline vibration and the liquidation are calculated coupled with the Winkler model of the soil. The vibration characteristic and the dynamic response of the suspended submarine pipelines are analyzed to provide scientific and reliable basis for the design and maintenance of the pipelines.
