拱桥缆索吊装施工关键技术研究

Study on the Key Construction Techniques of Cable Hoisting Construction of Arch Bridges

结合工程实例,从缆索吊装系统的设计、扣索扣挂顺序及索力调整、拱肋吊装等关键施工技术几个方面对大跨度钢管混凝土拱桥的无支架缆索吊装施工进行探讨,并给出一些合理的建议,供类似桥梁施工工程参考。

Combined with an engineering example, this paper discusses the construction of non-bracket cable hoisting for large span concrete filled steel tubular arch bridges. The key construction techniques in the construction process are discussed, including cable hoisting system design, cable system design, cable force adjustment and arch rib hoisting, and some reasonable suggestions are given at last. Research conclusion could provide reference for the similar bridge construction.
