| 摘 要： | 绥满公路上某座预应力混凝土高架桥出现了裂缝和挠度过大等病害,通过分析采用施加体外预应力和粘贴钢板的加固方案,并进行了加固计算和试验验证.结果表明加固后桥梁的变形、受力和裂缝都有了显著改善.这对以后悬臂施工的高架桥病害分析和加固具有一定的借鉴意义.

| Abstract: | Because diseases and damage,such as cracks and too much deflection,appear in a certain pre-stressed concrete viaduct of the Sui-Man Highway,the strengthening plan of external pre-stressing and sticking steel plates is applied to the viaduct,the effect of which is analyzed and tested in the paper.The result shows that the deflection,stress and cracking of the bridge are remarkably overcome.The project may serve as a useful reference for the analyses of the diseases and damage in and the strengthening of cantilever-constructed viaducts. |
