广东肇庆大桥桥面振动测试研究

Study on Zhaoqing Bridge Deck by Vibration Test

就肇庆大桥振动测试中所获得的结果进行分析 ,研究了有、无火车运行时所引起的振动对桥面铺装层的影响 ,证明火车在桥梁上运行所产生的振动对桥面辅装层的影响不大 ,桥面铺装层的破坏主要是路面材料及其级配的不合理所致 。

The vibration test results of Zhaoqing Bridge are analyzed.And the vibration's influence on the bridge deck surface is discussed under the circumstances of train load or none train load.It is proved that the vibration caused by train loads has little effect on the surface,cracks of the bridge deck are mainly caused by irrational pavement materials and their gradation,as well as construction processes.
