| 摘 要： | 白鹭大桥是一座无背索竖琴式斜拉桥,为了测试该桥的动力性能,通过跑车试验对白鹭大桥进行了频谱曲线和动位移测试,并且测试了该桥的自振频率和振动参数。通过动载试验及其数据的分析,对无背索竖琴式斜拉桥的工作性能给予客观的评估。试验对同类型桥梁的结构评定可起到一定的借鉴作用。

| Abstract: | The Bailu Bridge is a harp-shaped cable-stayed bridge with no back-stayed cables.To test the dynamic performance of the bridge,the frequency spectrum curves and the values of the dynamic displacement are obtained by the running test,and its natural frequency and vibration parameters are tested,too.By the dynamic loading test and through analyzing the test data,an objective assessment of its working performance is performed.The test may serve as a useful reference not only for harp-shaped cable-stayed bridges with no back-stayed cables,but also for other bridges of similar types. |
