城市快速路上跨高速公路方案研究

以南京市某条城市快速路上跨高速公路为例,该文提出2种设计方案进行比选,从既有高速公路建设条件、桥梁结构选型、施工期影响及工期要求等方面进行讨论,最终采用钢箱梁桥梁方案。并针对方案进行桥梁结构设计,编制节点施工流程,可为同类桥梁的建设提供一定参考。

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.
