| 摘 要： | 为准确评价韶关东跨线桥的实际承载能力,对其进行动静载测试。分析实测桥梁应变、应力、挠度、频率等数据。得出结论:静载作用下,该桥的应力校验系数、相对残余变位满足规范要求,结构处于弹性工作阶段;动载作用下,桥梁实测固有频率大于计算值,其动力响应在正常范围内,动力性能及承载能力满足设计要求。

| Abstract: | In order to evaluate the actual bearing capacity of Shaoguan East Bridge accurately, dynamic and static load test was carried out. Through analyzing measured data such as strain, stress, deflection and frequency of the bridge, we draw the conclusion: Under the action of the static load, the stress calibration coefficient and relative residual displacement meet the specification requirements, and the structure is in elastic stage; Under the action of dynamic load, the measured natural frequency is greater than the calculated value. The dynamic responses are in normal range. The dynamic performance and the carrying capacity meet the design requirements. |
