随着世界范围内深海石油开采的需要,近年来关于海洋结构物涡激振动的研究越来越受到重视.虽然此问题在数值模拟和实验方面都已取得了一定的进展,但是还有许多问题尚待解决.同时,新型海洋结构物的引入给涡激振动的预报方法和抑振手段提出了新的挑战.因此,细长海洋结构物的涡激振动仍将是未来几年里备受关注的研究课题.本文在介绍有关涡激振动基本概念和理论背景的基础上,总结了近年来关于以深水立管为代表的海洋结构物涡激振动的研究与进展,包括对现有涡激振动分析工具的分类与评估;对柱体及海洋结构物涡激振动的实验研究;对深水立管与涡激振动相关的疲劳评估准则的研究;海洋结构物的横向、流向及轴向涡激振动的耦合作用研究;关于海洋结构物涡激振动的抑振措施和设备的理论及实验研究.本文着重介绍了计算流体力学方法在海洋结构物涡激振动研究中的应用和进展.最后,对海洋结构物涡激振动相关的研究热点的现状进行了总结并对今后工作提出了展望.%With the increased interest in worldwide deep-water petroleum production, more efforts were put on the research activities on vortex-induced vibrations (VIV) during the past ten years. Despite much progress made both numerically and experimentally, it cannot be stated that a full understanding of VIV problem was achieved. The introduction of steel caternary risers (SCR) has presented new challenges for prediction and suppression of VIV. Therefore, VIV of slender marine structures will remain as one of the most extensive research topics of ocean engineering in the coming years. In this paper, the background and introduction of vortex-induced vibrations of marine risers is presented, which is followed by an overview of the research and progress concerning deepwater riser vortex-induced vibrations, including evaluation of existing VIV analysis tools, experiments together with data analysis and calibration, appropriate fatigue calculation criteria, coupling effects induced by axial and inline VIV, suppression device selection and testing. More attention is paid to the contribution made by the improving computational fluid dynamics (CFD) method. Conclusions and recommendations for future directions are addressed in the end.
