摘要
总结了梁拱组合桥梁设计现状,并以河北某地一座48 m+5×72 m+48 m斜交梁拱组合桥梁为例,简要介绍了项目基本情况及整体设计思路,对桥梁结构进行计算分析,阐述了该桥设计难点、创新点及相应的处理措施,包括梁拱组合桥梁景观方案确定,城市钢桥超宽桥面的处理,斜交钢梁节段处理等,以期为梁拱组合式桥梁设计提供参考。
The design status of beam arch composite bridge is summarized.Taking a 48 m+5×72 m+48 m skew continual beam arch composite bridge as an example,the basic situation and overall design idea of the project are briefly introduced.The structure of this bridge is calculated and analyzed.The design difficulties,the innovation points and the relevant countermeasures of the bridge are expounded including the determination of landscape scheme for beam arch composite bridge,the treatment of ultra-wide deck of urban steel bridge and the treatment of skew steel beam segments in order to provide the reference for the design of the similar beam arch composite bridges.
