| 摘 要： | 通过无障碍行车(跑车)试验和有障碍(跳车)试验,评价东江大桥的动力响应特性。实验结果表明,结构各部位反应平稳,无任何异常现象发生,实桥结构的动力性能良好。对比分析了不同试验工况的冲击系数和应变增大系数。结果表明,车辆对大桥的冲击系数因位置和速度而异;应变增大系数则与车速成反比。

| Abstract: | Through the barrier-free driving test and obstacles test the dynamic response characteristics of Dongjiang bridge is evaluated.The experimental results show that the various parts of structural response is smooth,without any abnormal phenomenon.Tt means the dynamic performance of Dongjiang bridge is really good.The impact factor and the strain magnification factor in different experimental conditions,are Comparatied and analysed The results show that the vehicles on the bridge's impact factor varies by posi... |
