直桩在水流作用下的动力计算及防止诱发共振的措施

Dynamic Calculation of Vertical Piles under Flow Action and Preventive Measures of Induced Resonance

由流诱发桩式结构物振动而导致破坏 ,国内研究较少 ,而国外已有较成熟的研究成果。文章主要介绍这些成果 ,并在此基础上推导了多桩结构 (如柔性靠船墩 )动力计算公式 ,并提出了防止流诱发共振的措施 ,可推广到类似结构的设计计算及规范编制中。

There is less research in China on the damages of piled structures due to vibration induced by water flow. But there are already mature research fruits on it abroad, which are introduced mainly in this paper. Based on these research fruits, dynamic calculation formulae for multi-piled structures (i.e. flexible breasting dolphin) are derived and preventive measures for flow-induced resonance are put forward, which may be generalized to design calculation and code compilation of similar structures.
