摘要
福州闽江长门大桥是国内首次采用塔梁固结体系的混合梁斜拉桥,主跨为550m。简要介绍了本桥的建设条件、方案构思、桥型总体设计和具体结构设计,并针对钢混结合段位置、结构体系选取、塔梁固结部位局部应力分析、结构抗风和抗震性能等关键技术问题的研究论证做了简要介绍。
Minjiang Changmen Bridge in Fuzhou City is a hybrid girder cable-stayed bridge used the pylon-girder fixed system for the first time in China, and the main span exceeds 550 meters. In this paper, the construction condition, design of bridge type and structure of this bridge are mainly introduced. The key techniques including the comparison between the differences sites of steel-concrete joint part,optimum of structures system, the local stress analysis of pylon-girder fixed region, structure property of the seis- mic and wind resistance performance, etc are specific discussed in this work.
