摘　　要：现行《公路桥涵设计通用规范》(JTG D60-2004)、《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004),较85规范在很多方面有实质性的改进,但是,《城市桥梁设计准则》(CJJ 11-93)及《城市桥梁设计荷载标准》(CJJ 77-98)与其存在着脱节的内容。探讨上述规范中城市桥梁的设计基准期、荷载组合及冲击系数等问题。In comparison to the codes in effect in 1985, the current General Code for Design of Highway Bridges and Culverts （JTG D60-2004） and Code for Design of Highway Rein-forced Concrete and Prestressed Concrete Bridges and Culverts （JTG D62-2004） have been substantially improved in many aspects. However, in the Norm for City Bridge Design （CJJ 11-93） and Norm for City Bridge Design Load（CJJ 77-98）, some of the provisions are not in good connection with those in the above two Codes. In this paper, several issues on the provisions of the design reference period, load combination and impact factors of city bridges not well connected with the Codes are studied.
