摘要
衢江大桥主桥为Y腿刚构单拱肋系杆拱桥,主桥孔跨布置为(50+120+50)m,拱肋、边跨主梁与Y形主墩刚性连接,边、中跨主梁设牛腿相连,中跨100m主梁通过吊杆与主拱相连,拱肋为钢箱拱,拱趾设水平系杆。主要介绍主桥结构特点、结构分析和施工方法。
The main spans of Qujiang River Bridge are of a rigidframe bowstring arch structure on Yshape piers with single arch rib, and with the spans arranged as (50+120+50) m. The arch rib and side spans are rigidly connected with Yshape piers, the side and main spans are connected each other by the aid of brackets, and the 100m mid\|span girder is connected with the arch through hangers. The arch rib is designed as steel box section, and horizontal tie rods are used at arch spring. In this paper, the structural features, structural analysis and construction method for the main spans of the Bridge are presented.
