Suspension bridge with four main cables with different vertical span ratios
The invention discloses a suspension bridge with four main cables with different vertical span ratios. The suspension bridge comprises a plurality of cable bent towers and two pairs of main cables symmetrical along the longitudinal center face of the bridge, the main cables are connected with a bridge floor through suspenders, the middles of the main cables are suspended through the tower tops of the cable bent towers, the ends of the main cables are fixed through cable saddles at the two ends of the bridge floor, each pair of main cables comprises an upper cable and a lower cable which are independent of each other, the vertical span ratio of the upper cable is smaller than that of the lower cable, the hanging heights of the upper cable and the lower cable at the tower top are the same, and the heights of midspan vertical points are different. According to the suspension bridge, the structural performance of the suspension bridge can be improved under the condition that the installation difficulty is reduced.
本公开涉及一种四主缆不同垂跨比悬索桥,包括多个索塔以及沿桥梁纵向中心面对称的两对主缆,主缆通过吊杆连接桥面,主缆中部通过索塔的塔顶悬挂,主缆端部通过桥面两端的散索鞍固定,每对主缆包括相互独立的上缆和下缆,上缆的垂跨比小于下缆,上缆与下缆在塔顶处悬挂高度相同、跨中垂点高度不同。本公开能够在减少安装难度的情况下,提高悬索桥的结构性能。
