摘　　要：该文以宁波北环快速路工程高架道路与轨道交通共建段为工程背景,通过建立有限元动力模型进行抗震分析,探讨了双层高架桥梁的结构体系、抗震性能,以及有别于常规桥梁的特殊之处。其成果对类似桥梁的设计与建设具有一定的参考意义。Taking the elevated road and rail transit construction section of Ningbo North Ring Expressway Project as the engineering background and establishing the finite element dynamic model for seismic analysis,the article discusses the structural system and seismic performance of double-deck viaduct as well as the special part different from the conventional bridges. The result can be referred for the design and construction of thesimilarbridges.
