| 摘 要： | 随着交通工程的高速发展,作为连接道路的桥梁,起着至关重要的作用。由于长期超载以及收缩徐变等原因,某钢管混凝土系杆拱桥出现了包括拱肋下挠、钢管混凝土脱空、拱座裂缝、系杆及吊杆锈蚀等病害,在对该桥进行综合检测的基础上,采取一系列的加固措施,通过一段时间运营后,表明这些措施有效缓解了结构的现有病害,加固效果良好,可供类似桥梁工程的加固设计参考。

| Abstract: | The bridge of linking road plays a very important role with rapid development of traffic engineerings.Due to the reasons such as shrinkage,creep and long-term overloaded,a comprehensive test with the defects,such as arch rib deflection,concrete slab,crack,corrosion of tie bar and suspender etc was done on a CFST tied arch bridge.Based on the inspection and test results,the bridge was then strengthened with several methods.Through a period of time after its operation,the results showed that the strengthening procedures mentioned above could effectively slow down the existing deteriorations,these reinforcement effects were good,which could be referred by the reinforcing design of similar bridges. |
