摘　　要：随着桥梁跨径的不断增大 ,悬索桥的颤振稳定问题日益突出。本文以风洞试验为基础 ,研究了中间开槽截面的颤振稳定性 ,并测得这种截面的形状修正系数。结果表明 。The flutter stability of suspension bridge is becoming more and more important with increase of the span. This paper studies the flutter stability of bridge box girder with a central slot and identifies the modified form factor based on the wind tunnel test. Results show the slotted section would be helpful for improving the flutter behavior of suspension bridge.
