Highway-railway dual-purpose box girder composite girder bridge with cantilever arms
The embodiment of the invention provides a highway-railway dual-purpose box girder composite girder bridge with cantilever arms. The highway-railway dual-purpose box girder composite girder bridge comprises a steel box girder, two main trusses, a highway bridge deck system and a railway bridge deck system. The steel box girder comprises a box body and the two cantilever arms, and the two cantilever arms are arranged on the two transverse sides of the box body. The two main trusses are arranged on the lower side of the steel box girder, each main truss comprises a lower chord member and a plurality of web members, the two main trusses are arranged at intervals in a transverse bridge direction, and the web members are connected with the lower chord members and the box body; the highway bridge deck system comprises a highway bridge deck, and the highway bridge deck is arranged on a steel box girder; and the railway bridge deck system comprises a railway bridge deck slab and a plurality offirst cross beams, the first cross beams are connected with the lower chords of the two main trusses, and the railway bridge deck slab is arranged on the first cross beams. The highway-railway dual-purpose box girder composite girder bridge with the cantilever arms has a high transverse and vertical bending moment resistance and a high spanning capacity, and the transverse and vertical rigidity of the highway-railway dual-purpose box girder composite girder bridge can meet running requirements of high-speed trains.
本申请实施例提供了一种带挑臂的公铁两用箱桁组合梁桥，包括钢箱梁、两个主桁架、公路桥面系和铁路桥面系。钢箱梁包括箱体和两个挑臂，两个挑臂设置在箱体的横向的两侧；两个主桁架设置在钢箱梁下侧，主桁架包括下弦杆和多个腹杆，两个主桁架沿横桥向间隔设置，多个腹杆连接下弦杆和箱体；公路桥面系包括公路桥面板，公路桥面板设置在钢箱梁上；铁路桥面系包括铁路桥面板和多个第一横梁，多个第一横梁连接两个主桁架的下弦杆，铁路桥面板设置在多个第一横梁上。本申请实施例的带挑臂的公铁两用箱桁组合梁桥具有较大的横、竖向抗弯矩性，跨越能力大，且其横向和竖向的刚度能够满足高速列车的行车要求。
