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 ,为国内同类型桥梁的加固设计与施工积累了实践经验
This paper introduces the condition of the main bridge with multi-span prestressed concrete continuous box girder with main span of 80 m and its reinforcement. The reinforcement of this bridge has successfully created a large volume of concrete in the box with continuous beam reinforcement The precedent of spanning continuous span bridges with medium span has accumulated practical experience in the design and construction of the same types of bridges in China
