摘要
以湖南省岳阳洞庭湖大桥斜拉索风雨振现场观测试验采集的有效数据为依据,定量分析了风速、风向角、雨量与拉索振动的关系,风场参数对气动负阻尼比的影响。据此,对风雨振研究工作提出了一些建议。
On the basis of the effective data collection from the field experimental tests of wind-rain induced stay cable vibration on Dongting Lake Bridge in Hunan Province, makes a quantitative analysis on the relationship between wind speed, wind declination, rainfall and cable vibration as well as the impact of wind field parameters on the aerodynamic negative damping ratio. Accordingly presents some suggestions on the research of wind-rain induced stay cable vibration.
