| Abstract: | In recent years, many high - span structure of the bridge for various reasons leading to the quality acci- dent occurs, most of which is due to under- specification result in concrete construction. In this paper, a continuous box girder bridge cracks in the quality of the capping beam diseases, both from the design and construction analysis of the causes of cracks and based on the stress calculation results, provide the corresponding reinforcement measures, bridge operators so far, no further cracks development, and achieved good results. |
