摘要
介绍了主跨为 80 m的多跨预应力混凝土变截面连续箱梁主桥的病害情况及加固处理 ,本桥加固成功开创了在维持通车情况下在箱内浇注大批量混凝土配合体内束加固多跨中等跨径连续梁桥的先例 。
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.
