| 摘 要： | 飞来峡水利枢纽溢流坝运行工况复杂，存在不利的水流现象，对闸墩和闸室结构产生振动作用，必须进行结构动力设计。设计通过对结构流激振动研究成果进行分析，采用水工模型和水弹性模型的实测数据作为设计参考的参数，并与有限元分析的结果互相印证。采取在闸墩尾部增设人行工作桥的减振措施，使闸墩振幅和闸墩动应力大为减少，结构设计更加合理可靠。

| Abstract: | Since the spillway of Feilaixia Project operates in complicated mode,unfavourable flow phenomenon causes vibration to peirs and gate chamber structure.It is essential to carry out structural dynamic design.On the basis of analizing the results obtained by reserch on vibration excited by current on the structure,data measured in hydraulic model and water elastic model are used as parameters for design reference and verified with results of finite element method.As vibration reduction measure,foot bridge is added to peir tail to reduce the amplitude of vibration and dynamic stress of the peir to make the structural design more rational and reliable. |
