文章分析和比较了加固前后泉州大桥的动力特性,并且分析和评估了泉州大桥加固前后在设计荷载等级-汽-20以及超载等级-挂-120和城-A静力性能。分析结果认为:(1)加固提高了泉州大桥的使用性能和耐久性;(2)加固对泉州大桥的整体静动力性能影响较小;(3)加固前后泉州大桥均能满足设计荷载以及挂-120和城-A的荷载等级要求。
The paper analyzes and compares the dynamic characteristics of Quanzhou Bridge before and after reinforcement, and analyzes and evaluates the static load at the design load level-steam-20 and the overload level-hang-120 and the city-A static performance before and after the reinforcement of Quanzhou Bridge. The results show that: (1) The reinforcement improves the serviceability and durability of Quanzhou Bridge; (2) The reinforcement has little effect on the overall static and dynamic performance of Quanzhou Bridge; (3) Before and after the reinforcement, Quanzhou Bridge can meet the design load and hang- 120 and city-A load level requirements.
