| Abstract: | 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. |
