重载条件下32m梁式桥振动特性试验研究

Test on vibration feature of 32 m beam bridge under heavy loading situation

通过对重载条件下32 m梁桥的动载试验,了解桥梁结构的振动特征,对相关数据进行了分析汇总,据以判断结构在动载作用下的安全工作状况,从而为重载桥梁加固设计积累经验。

Through the dynamic load test to the 32 m beam bridge under heavy load,so as to know the vibration feature of beam structure,the paper analyzes relative data thus to judge the safe working situation under dynamic loading situation,so as to accumulate experiences for the enforcing design of the heavy loading bridge.
