府河大桥人字形桥塔施工关键技术

Construction key techniques for“human”shape bridge tower of Fuhe bridge

府河大桥作为130+85 m的独塔单索面斜拉桥,索塔侧面采用了“人”字形的形状。目前关于异型桥塔的施工研究比较匮乏,因此其桥塔的施工特点值得研究。结合工程案例和Midas软件验算结果,对“人”字形索塔施工的关键技术进行分析,为日后同类斜拉桥的建设与发展提供宝贵经验。

Fuhe Bridge is a 130+85 m cable-stayed bridge with a single tower and a single cable plane.The lateral side of the tower is in the shape of a“human”.At present,the research on the construction of special-shaped towers is scarce,so the construction characteristics of the towers are worth studying.Based on the engineering case and the results of Midas software verification,this paper analyzes the key technologies for the construction of“human”towers and provides valuable experience for the construction and development of similar cable-stayed bridges in the future.
