摘　　要：我国现行的公路、铁路桥梁钢结构设计规范落后于桥梁建设的发展,以至于在桥梁钢结构和组合结构设计与计算中一些问题无相应规范可依据。通过一座主跨100 m的钢箱拱肋组合桥面系提篮拱桥为例,对受压钢箱拱和钢-混凝土组合结构设计与计算中的几个问题参考国外相关规范进行了一些探讨,为同类桥梁钢结构与组合结构设计提供参考。Our country＇s code for design of highway and railway steel bridge structures is getting behind the development of bridge construction, which account for the lacking of relevant codes on some problems in design and calculation of steel and composite bridge structures. This paper takes a 100 m main-span lifting basket arch bridge with composite beam deck system of steel box girder arch rib for example, then discuss the aforementioned problems refer to some foreign codes and offer reference to the design of some bridges
