摘　　要：为了解广州某斜拉桥的结构技术状况,评定结构实际承载能力,文中通过静、动载试验对结构控制截面的响应参数进行测试,并采用有限元方法建立该桥计算模型,将试验实测值与理论计算值进行对比分析。结果表明:控制截面关键测点的试验实测数据与理论计算结果基本一致,且均小于理论值,整体动力刚度满足设计要求,可为同类型桥梁的荷载试验分析提供参考。In order to understand the technical status of a cable-stayed bridge in Guangzhou,and evaluate the actual carrying capacity of the structure,the response parameters of the control section of the structure are tested by static and dynamic load tests,and the calculation model of the bridge is established by finite element method,then the measured values are compared with the calculated values.The results show that the measured data of key measurement points of the control section are basically consistent with the theoretical calculation results,and the overall dynamic stiffness meets the design requirements,which can provide a reference for load test analysis of the same type of bridge.
