装配式桥梁上部结构选型探讨

从钢板组合梁、钢混组合箱梁、钢混组合桁架梁、波纹钢腹板钢混组合梁几个方面详细阐述了装配式桥梁的上部结构选型,以应对蓬勃发展的绿色城市理念提出的经济、低碳、工厂化程度高、标准化的装配式桥梁需求。对几种可供装配式桥梁选用的上部结构形式的构造、特性及注意要点进行深入探讨,为装配式桥梁的发展提供借鉴。

Discussion on Superstructure Selection of Fabricated Bridge

This paper sets forth the superstructure selection of fabricated bridge from several aspects of steel plate composite beam,steel-concrete composite box beam,steel-concrete composite truss beam and corrugated steel web steel-concrete composite beam in detail,and puts forward the economic,low-carbon,high industrialization degree and standardizing demands of fabricated bridge in response to the burgeoning concept of green city.This paper further discusses the constructions,characteristics and key attentions of several superstructure forms able to be selected for the fabricated bridges,which can be referred for the development of fabricated bridges.
