Abstract

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.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a continuous steel truss combined girder bridge and a construction method for high-speed railway combined construction of highway and railway. Background technique [0002] With the increase of my country's investment in infrastructure, the construction of high-speed railways and passenger dedicated lines has led to a large increase in the number of bridges, and the number of bridges built in conjunction with high-speed railways and railways is bound to increase. [0003] However, in the related art, the steel consumption of the road-rail combined bridge with a design speed of 350km / h is relatively large, and the project cost is uneconomical. And rigidity is weaker, and the driving condition of train is poorer. Contents of the invention [0004] In view of this, the main purpose of the embodiment of the present application is to provide a continuous steel truss combined girde...
