Highway-railway combined construction continuous steel truss combined beam bridge of high-speed railway and construction method
The embodiment of the invention provides a highway-railway combined construction continuous steel truss combined beam bridge for a high-speed railway. The highway-railway combined construction continuous steel truss combined beam bridge comprises a steel truss beam, a highway bridge deck system and a railway bridge deck system. The steel truss beam comprises two main trusses and a plurality of upper transverse tie beams. Each main truss comprises an upper chord member, a lower chord member and a web member. The upper transverse tie beam is connected with the upper chord members of the two maintrusses; the highway bridge deck system comprises a concrete bridge deck slab and a plurality of concretetransverse beams. The concrete bridge deck slab is connected with the upper chord members of the two main trusses through shear nails; the railway bridge deck system comprises an orthotropic steel bridge deck slab and diaphragm beams, the orthotropic steel bridge deck slab is connected with the lower chord members of the two main trusses, and the multiple diaphragm beams are arranged on the lower side of the orthotropic steel bridge deck slab. The embodiment of the invention further provides a construction method of the highway-railway combined construction continuous steel truss combined beam bridge of the high-speed railway. According to the highway-railway combined construction continuous steel truss combined beam bridge of the high-speed railway and the construction method, the construction cost can be reduced while the structural rigidity is improved, and the road surface driving condition is improved.
本申请实施例提供了一种高速铁路公铁合建连续钢桁结合梁桥，包括：钢桁梁、公路桥面系和铁路桥面系；钢桁梁包括两个主桁架和多个上横系梁，主桁架包括上弦杆、下弦杆和腹杆；上横系梁与两个主桁架的上弦杆连接；公路桥面系包括混凝土桥面板、以及多个混凝土横梁；混凝土桥面板与两个主桁架的上弦杆之间通过剪力钉连接；铁路桥面系包括正交异性钢桥面板和横隔梁，正交异性钢桥面板与两个主桁架的下弦杆连接，多个横隔梁设置在正交异性钢桥面板的下侧。本申请实施例还提供了一种高速铁路公铁合建连续钢桁结合梁桥的施工方法。本申请实施例的高速铁路公铁合建连续钢桁结合梁桥及施工方法在提高结构刚度的同时，能够降低工程造价、改善路面行车条件。
