某斜跨拱桥维修设计与施工控制研究

Research on Maintenance Design and Construction Control of an Oblique-span Arch Bridge

以某斜跨拱桥应急抢险工程为背景,介绍了该桥在运营阶段出现的病害并分析了原因,阐述了其维修设计的主要内容,并对施工过程进行了控制。针对主梁侧移这一主要病害,采用销轴式约束取代传统限位装置取得了较好效果,目前该桥运营良好。

Taking the emergency rescue project of an oblique-span arch bridge as the background,the diseases that occurred during the operation phase of the bridge are introduced,the reasons are analyzed,the main content of its maintenance design is elaborated,and the construction process is controlled.In response to the main disease of lateral displacement of the main beam,the use of pin type constraint instead of the traditional limit device has achieved good results,and the bridge is currently operating well.
