摘要
Abstract
The constraint system of steel truss girder bridge support is different from that of traditional girder bridge structure,and the selection of its design scheme affects the size of the bridge substructure and the selection of supports.Combined with engineering examples,the influence of simply supported structure,continuous structure,two trusses,three trusses and other factors on the design of the support restraint system of steel truss girder bridges is analyzed,and the design countermeasures such as improving the horizontal bearing capacity of the support design and releasing the longitudinal slip restraint of the truss in the three trusses are proposed,which can provide reference for similar bridges.关键词
