合肥市当涂路大桥修缮工程工艺浅述

The Repair Work Process of Dangtu Road Bridge of Hefei

合肥市当涂路大桥的结构形式是钢筋混凝土箱型系杆拱桥,在运行了将近10年时间后,特别是近几年交通量不断增加,超载、超重车辆较多,导致桥面板破坏、断裂,使全桥许多部位出现裂缝。文章介绍了在不改变大桥的结构体系,加固补强和修缮相结合,充分利用原有主体结构下构及上构的主拱圈、吊杆、纵横梁,对检测中发现的因受力产生的病害进行针对性的加固补强处理措施。

Dangtu Road Bridge of Hefei is a RC tied-arch bridge with box-shaped arch ribs. And after nearly ten years of service and under a growth of traffic volume and overloaded vehicles in the past few years, there are damages and fractures in the deck and cracks in many parts of the bridge. The repair work is done when the structure of the bridge remains unchanged to make the most of the old main arch ring, suspender and longitudinal and transverse beam and to reinforce the failure parts that are disabled by stress.
