钢管混凝土拱桥典型病害分析研究

Analysis and Study on Typical Disease of Concrete-filled Steel Tubular Arch Bridge

早期兴建的钢管混凝土拱桥或多或少地存在着设计、施工等方面的局限性,后期缺乏必要的养护和维修。随着桥梁结构老化,营运量不断增加,使得钢管混凝土桥梁病害时有发生。有鉴于此,该文结合依托工程及相应的结构检查,详细介绍了钢管混凝土拱桥的病害特征及其原因,从而为该类桥梁的安全状况评估提供参考借鉴。

The limitation of the concrete-filled steel tubular arch bridge built early sometimes occurs in the design and construction, and the necessary maintenance and repair are lack later. With the aging of the bridge structure, the continuous increment of transport quantity makes the disease occur in concrete-filled steel tubular arch bridge sometimes. In view of this, the article introduces in detail the disease character and its cause of this arch bridge so as to evaluate the safe status of this bridge according to the relative projects and the relative structure inspection able to be for reference.
