Arch bent frame suspension bridge structure
The invention relates to an arch bent frame suspension bridge structure which comprises a longitudinal main beam, a plurality of groups of transverse and parallel arch ribs are arranged over the mainbeam and stretch across the main beam, and vertical slings are arranged between the arch ribs and the main beam. Compared with a continuous beam adopting portal piers, the portal piers are replaced bythe arch ribs, so that the structure looks more beautiful; and the supporting mode of sling suspension is used for replacing support supporting, the building height of the main beam is reduced, and the problem of under-bridge clearance tension is solved. Compared with a cable-stayed bridge, the span of the main span is reduced, and the manufacturing cost is reduced; arrangement is flexible, and the structure is better adapted to plane curve shapes at the bridge positions; meanwhile, the invention also provides a choice for small-angle crossing of the existing road for route design, and is a bridge structure with stronger applicability.
本发明涉及一种拱形排架悬吊桥梁结构，所述结构包括纵向的主梁，主梁上方设置多组横向且互相平行的拱肋并横跨主梁，拱肋与主梁之间设置有竖向的吊索。本发明相比采用门架式墩的连续梁，用拱肋替代了门架墩，景观性更好；用吊索悬吊的支撑形式代替了支座支撑，降低了主梁建筑高度，解决了桥下净空紧张的问题。相比斜拉桥，减小了主跨跨径，降低了造价；布置灵活，更适应桥位处平面曲线线形；同时，本发明也为路线设计提供了一种小角度跨越既有道路的选择，是一种适用性较强的桥梁结构。
