提高大跨悬索桥颤振临界风速的气动措施研究

Research on increasing the air-operated steps of large span suspension bridge flutter critical wind velocity

指出了提高大跨悬索桥颤振临界风速的措施有很多,而气动措施常为研究考虑的重点。通过对一主跨1 280 m的悬索桥的风洞模型抗风试验,对此进行了研究探索,结果表明,在主梁上增加风嘴可作为一种有效措施加以实施。

It points outithat the steps of increasing the large span suspension bridge flutter critical wind velocity, and the air-operated step is mainly considering the research, through the experiment to 1280 m span suspension bridge tuyere model anti-wind, it gets the research, and the affect proofs that it can be a effective steps to carry out of adding tuyere in main beam.
