Combined arch segment structure, bridge and construction method
The invention provides a combined arch segment structure, a bridge and a construction method, relates to the technical field of bridge engineering, and aims to solve the problems that an existing stiff skeleton arch bridge adopts a concrete wrapping skeleton for cooperative stress, the stress state of the whole structure is complex, and the risk of web cracking exists. The truss structure formed by the web members is adopted to replace concrete webs, the overall structure is clear in stress, prefabricated assembly construction can be conducted, and stress analysis and later maintenance are convenient to conduct; the structure comprises a middle box and side boxes connected to the two sides of the middle box respectively. Each side box comprises arch plates, chord members and web members, the at least two arch plates are sequentially arranged in parallel at intervals, at least two chord members are sequentially embedded in each arch plate, and the web members are connected between the opposite chord members in the adjacent arch plates to form a truss structure; a middle plate and a plurality of first transverse supports are connected between the two side boxes corresponding to the same middle box, the two ends of the middle plate are connected with the arch plates of the different side boxes, and the middle plate and the connected arch plates are coplanar.
本公开提供一种组合拱节段构造、桥梁及施工方法，涉及桥梁工程技术领域，针对目前劲性骨架拱桥采用混凝土包裹骨架协同受力，整体结构受力状态复杂、存在腹板开裂风险的问题；采用腹杆形成的桁架结构替代混凝土腹板，整体结构受力明确，且能够进行预制装配化施工，方便进行受力分析和后期维护；包括中箱和中箱两侧分别连接的边箱；边箱包括拱板、弦杆和腹杆，至少两块拱板依次间隔且平行布置，每个拱板内依次埋设有至少两根弦杆，相邻拱板内正对的弦杆之间连接多根腹杆，以形成桁架结构；同一中箱对应的两个边箱之间连接有中间板和多根第一横撑，中间板两端连接相异边箱的拱板，中间板与所连接的拱板共面。
