| 摘 要： | 以福建省闽清县雄江大桥为工程背景,结合实桥的动力试验和有限元计算对旧钢筋砼箱型拱桥的动力特性进行分析。结果表明,该桥在桥墩、拱座、拱圈加固后,结构的自振特性与有限元计算结果比较吻合;桥梁大部分振型的实测频率稍大于理论值,反映该桥跨结构的整体性、竖向刚度和抗扭刚度均有了较大幅度的提高。

| Abstract: | Based upon Xiongjiang Bridge which located at Minqing County, Fujian Province, analysis on dynamic property about old reinforced concrete box arch bridge is conducted by dynamic test and finite element method. It indicated the bridge's vibration property is closed to the result computed by finite element method after being strengthen.Most tested value of vibration mode is only a little larger than theoretical value, which shows torsional rigidity, vertical stiffness and integrality of the structure have increased to a large degree. |
