| 摘 要： | 以三峡水利枢纽溢流坝段与厂房坝段之间的导墙流激振动问题为背景，总结了导墙结构的脉动压力的幅频特征，计算分析了其流激振动响应，并与水弹性模型试验成果进行比较，探讨了三峡导墙流激振动的主振源，最后对导墙结构特征与流激振动安全性的关系进行了讨论，结果对类似工程有参考价值.

| Abstract: | This paper deals with the flow induced vibration of guide wall in the Three Gorges Project.The properties of the amplitude and frequency spectra of fluctuating pressure on guide walls are summarized.The responses of flow induced vibration of the guide wall are calculated and compared with the results of the hydroelastic model.The main excitation source is also studied.Finally,the safety of guide walls suffered from induced vibration is evaluated. |

| Keywords: | guide wall fluctuating pressure flow induced vibration hydroelastic model |
