Large-span double-helix forked arched girder combined footbridge structure system
The invention discloses a large-span double-helix forked arched beam combined foot bridge structure system. The structure system comprises double-helix arch ribs, rigid suspenders, straining beams, a bridge deck system, forked side spans and bridge piers. The whole bridge is provided with two double-helix arch ribs; the straining beam and the two double-helix arch ribs are connected into a whole to jointly form a stress structure system of the arch beam combination. The bridge deck system is located at the tops of the straining beams, provides a bridge deck for the bridge and directly bears live loads of crowds. One end of the forked side span is connected with the middle span, and the other end of the forked side span is connected with the embankment through a forked side span structure; the bridge piers are used for bearing loads transmitted by an upper structure, the bridge piers are arranged at the intersection of the double-spiral arch ribs under the bridge in the longitudinal bridge direction, and the forked Y-shaped bridge piers are adopted to provide necessary space for arrangement of the arch ribs. The three-dimensional space double-helix curve arch rib is adopted, and the three-dimensional space double-helix curve arch rib has the advantages of being good in stress performance, graceful in landscape performance, wide in view field and navigation clearance, ingenious in shore connection design, mature and simple in construction technology and the like.
本发明公开了一种大跨度双螺旋分叉式拱梁组合人行桥结构体系，该结构体系包括双螺旋拱肋、刚性吊杆、系梁、桥面系、分叉式边跨及桥墩；全桥设置两片双螺旋拱肋；系梁与两片双螺旋拱肋连接成整体共同形成拱梁组合的受力结构体系；桥面系位于系梁的顶部，为桥梁提供桥面并直接承受人群活载；分叉式边跨一端与中间跨相连，另一端采用分叉式边跨结构与堤岸连接；桥墩用于承受上部结构传递的荷载，桥墩纵桥向设置于桥下双螺旋拱肋交汇处，采用分叉式Y型桥墩给拱肋布置提供必要的空间；本发明采用三维空间双螺旋曲线拱肋，具有良好的受力性、优美的景观性、开阔的视野及通航净空、巧妙的接岸设计及施工工艺成熟简单等特点。
