摘要
通过桥梁节段模型风洞试验测量了桥梁的风力 ,研究了桥面护栏和隔离带以及变模型长度对模型风力的影响 ,并分析了桥的驰振稳定性和颤振稳定性 .试验结果表明 :设计试验方案以及应用试验结果时应考虑模型长度、桥面护栏及隔离带的影响 .
This paper introduces bridge section model tests in the wind tunnel.It presents static forces on bridge section models.The effects of bridge fences,isolation belts and different model lengths on static forces are studied.The static and dynamic stabilities of bridge are analyzed.The results show the effect of bridge fence,isolation belts and different model lengths on static forces should be considered in wind load design.
