斜交板桥横桥向位移原因分析及处治措施

针对一座大角度斜交的空心板桥梁出现的横桥向位移等病害，从力学分析的角度分析了该桥产生病害的主要原因。相关调查资料表明，大多数简易支座斜交板桥存在缓慢下滑和平面内转动的现象，其主要原因是横向下滑力和平面内不平衡力矩。据此提出了该桥的加固处理对策，并对今后进行斜交板桥设计和施工提出了建议，以期引起同行对此类型桥梁病害的重视。

Analysis and reinforcement measure for oblique hollow slab bridge that moves horizontally

For horizontal displacement disease of a large Angle oblique hollow slab bridge,the main cause disease is produced from the view of the mechanical analysis.Related survey data shows that the majority simple supports Oblique Itabashi are down slowly and in-plane rotation,the main reason is lateral down-slide force and in-plane unbalance moment.According to the analysis,the bridge reinforcement measure is proposed,and the future design and construction of Oblique Itabashi are suggested,in order to bring high ...
