摘　　要：随着我国城市交通基础设施建设的飞速发展,现有道路的上跨公路及城市立交桥越来越多。该类桥梁施工受下穿道路通行的影响非常大。为了减少对现有道路交通的影响,缩短工期,降低风险和管理难度,采用钢-混组合梁桥比较适宜。钢-混组合结构是在钢筋混凝土结构和钢结构的基础上发展起来的一种新型结构,它与混凝土箱梁相比极大地减轻了结构自重,提高了桥梁的跨越能力;与钢梁相比减少了钢材用量,提高了结构刚度。因此,钢-混组合梁桥在我国公路及城市立交桥建设中应用广泛。With the rapid development of urban transportation infrastructure in China,more and more highways urban overpasses are emergency across existing roads.The construction of such bridges is greatly affected by the traffic on roads below.In order to reduce the impact on traffic of existing roads,shorten the construction period and decrease hazards and management difficulties,steel-concrete composition bridges should be constructed,which are novel structures developed based on reinforced concrete structures and steel structures.Compared with concrete box beams,they can largely reduce the structural weight and improve the capacity of crossing bridges.Compared with steel beams,they are conducive to reducing the steel consumption and improving the structural stiffness.Therefore,steelconcrete composition bridges have been widely applied in highway and urban overpass construction in China.
