摘要
单板受力病害严重影响桥梁的使用安全,会造成桥面铺装和绞缝结构的损害,破坏桥梁功能的整体性,引起荷载横向分布不利变化和桥面板的内力集中,如不及时处理,会使桥梁承载能力进一步降低和使桥面板产生结构性破坏。故研究分析如何避免桥梁单板受力病害的产生以及更有效地处理现有病害,成为当前非常迫切的一项任务。
Veneer force diseases seriously affect the application security of bridges, lead to bridge pavement and hinge joints structure damages, destruct functional integrity of bridges, and cause adverse changes of lateral load distribution in the bridge deck and internal forces concentration. If not handle immediately, further reduce the load capacity and cause structural damage of bridge. It＇s becoming a very urgent task that studying how to avoid bridge veneer force diseases and to effectively deal with existed diseases.
