摘  要：以南京市某條城市快速路上跨高速公路為例，該文提出2種設(shè)計(jì)方案進(jìn)行比選，從既有高速公路建設(shè)條件、橋梁結(jié)構(gòu)選型、施工期影響及工期要求等方面進(jìn)行討論，最終采用鋼箱梁橋梁方案。并針對(duì)方案進(jìn)行橋梁結(jié)構(gòu)設(shè)計(jì)，編制節(jié)點(diǎn)施工流程，可為同類橋梁的建設(shè)提供一定參考。

Abstract： Taking an urban expressway in Nanjing as an example， this paper puts forward two design schemes for comparison and selection， and discusses the construction conditions of the existing expressway， the selection of bridge structure， the influence of construction period and the requirements of construction period. Finally， the steel box girder bridge scheme is adopted. According to the scheme， the bridge structure is designed and the joint construction process is compiled， which can provide some reference for the construction of similar bridges.

Keywords： urban expressway; upper span; existing highway; scheme comparison and selection; main line brige
