摘要
介绍了某钢管混凝土拱桥动力荷载试验过程,并对试验数据进行分析,试验结果显示试验边跨汽车冲击效应十分显著,且与车速有明显的相关性,汽车动荷载作用下,拱肋结构的动力响应性能异常,需引起高度重视,建议采取有效的措施对边跨主拱圈及垫梁等部位的开裂情况进行定期检查,希望本工程相关经验能为同类工程提供借鉴。
Firstly some concrete filled steel tube arch bridge dynamic loading test process is introduced.And the test data is analysed.The results show that automobile shock effect of the testing side is very notable,and it has obvious corelation with speed.Under automotive dynamic loading,the dynamic response of the arch rib structure is anomalous,which needs to be pay more attention.The crack situation of the sidespan main arch ring and mat beam is advised to take effective measures periodically.The relevant experience of this engineering may provide a reference for similar projects.
