| Abstract: | The situation,analysis and reinforcing treatment of defects of the main bridge of an extralong bridge are introduced. This main bridge is a multi span prestressed concrete continuous box girder bridge with variable cross sections and 80 m main span.Its succeeded reinforcement creates a precedent to reinforce that kind of bridge with posttensioned cables and large quantities of cast in place concrete under unceasing traffic,and accumulates design and construction experience in reinforcing the similar kind of bridges in China. |
