摘　　要：文章以浙江省某高速公路下承式钢管混凝土简支系杆拱桥为工程实例,对其进行交工桥梁外观检查、静载试验和动载试验,与有限元计算结果对比,分析桥梁结构静力和动力响应。试验表明,桥梁整体工作性能良好,具有承受预定设计荷载的强度和刚度,研究结果可为同类型桥梁结构的交工验收提供技术支持。Taking a through concrete-filled steel tube simply-supported tied arch bridge of an expressway in Zhejiang Province as an engineering example,the handover appearance inspection,static load test and dynamic load test of the bridge are carried out.Compared with the finite element calculation results,the static and dynamic responses of the bridge structure are analyzed.The test shows that the overall working performance of the bridge is good,and it has the strength and stiff ness to withstand the predetermined design load.The research results can provide technical support for the handover acceptance of the same type of bridge structure.
