| Abstract: | The problem of cracking under anchor at the web of Segment No.0 of a continuous rigid-frame box girder bridge occurred in the construction.The causes leading to the cracking are analyzed from both aspects of design and construction and specific proposals to improve the design and to handle the cracking are made.The follow-up construction implementation of the bridge proves that the design improvement by proper layout of reinforcement through calculation and strict quality control in the construction are successful. |
