连续箱梁体外预应力加固施工技术

Technology for Construction of Pre-stressed Strengthening Outside of Continuous Box Girder

以301省道府保黄河二桥加固应急处治工程为例,采取增设体外预应力及腹板加厚等技术措施对该桥进行加固改造,重点阐述连续箱梁体外预应力加固施工技术。实践证明301省道府保黄河二桥加固改造成功,为同类工程积累可参考的经验。

Such as 301 provincial road Fu Bao Yellow River Second Bridge reinforcement emergency treatment project as an example,Taking technical measures such as increasing Pre-stressed Outside of Continuous Box Girder and the thickness of the web to strengthen the bridge,Focus on the technology for Construction of Pre-stressed Strengthening Outside of Continuous Box Girder.Practice has proved that the 301 provincial road Fu Bao Yellow River Second Bridge reinforcement emergency treatment project have been successful,which can be used as reference for similar projects.
