某大桥引桥箱梁翼板悬臂根部纵向裂缝加固设计与施工技术研究

Study on Reinforcement Design and Construction Technology for Longitudinal Crack of Cantilever Beam of Box Girder Flange Bridge of Approach Bridge

在某大桥例行检查中,发现其引桥箱梁翼板悬臂根部上缘桥面沥青有明显纵向裂缝。为保证该大桥运营安全,必须对箱梁进行加固设计与施工。

In the routine inspection of bridges,it is found that there are obvious longitudinal cracks in asphalt on the upper edge of the cantilever root of the flange plate of the approach box girder of the bridge.In order to ensure the safe operation of the bridge,the design and construction of the box girder must be strengthened.
