摘要
本文分析了采动影响下钢筋混凝土结构桥梁构对的损害特征，结合桥梁结构特点和受损维修的可能性．对其构件的损害程度进行了分类。依据有关规程及“三下”采煤经验．参照钢筋混凝土受弯构件弹塑性变形机理。
Based on the analysis of the damage features of reinforced concrete bridge caused by underground mining,the damage degree of the bridge components have been classified,through combining the bridge Structure characteristics with its maintenance possibility in this paper.The deformative limit of bridge components have been analysed according to the bridge standard, mining subsidence standard,coal mining experience and the elastic-plastic deformation mechanism of the reinforced concrete bending component.
