摘　　要：以某景区大跨度人行悬索桥为背景,采用节段模型风洞试验,分别研究了原设计断面和四类气动措施方案的风致振动性能。结果表明:采用下中央稳定板可以有效提高板式加劲梁人行悬索桥的颤振稳定性,可为类似桥梁断面的设计提供参考。Taking a large-span pedestrian suspension bridge in a scenic area as example,a wind tunnel test with segmental model was used to study the wind-induced vibration performance of the original design section and four kinds of aerodynamic measures.The results showed that the flutter stability of the slab stiffened beam pedestrian suspension bridge can be improved effectively by using the lower central stabilizer plate,which can provide reference for the design of similar bridge sections.
