摘　　要：新典桥位于浙江省宁波市,主桥为跨径213 m(桥长221.6 m)下承式简支系杆拱桥,一跨跨越奉化江.结合新典桥桥位的周边环境,综合考虑通航、周边环境等限制因素,对各类施工方案进行分析和比选,最终采用了拱梁整体步履式顶推施工.宁波新典桥是国内少见的采用拱梁整体顶推施工的桥梁,也是宁波市第一座采用该施工工艺的桥梁,对于宁波市乃至全国的桥梁建设具有重大意义,对于同类型施工方法的桥梁具有一定的借鉴意义.Xindian Bridge is located in Ningbo City,Zhejiang Province.The main bridge is a through simple-supported bowstring arch bridge with a span of 213 m(bridge length 221.6 m),and one span crosses Fenghua River.Combined with the surrounding environment of Xindian Bridge,considering the navigation,surrounding environment and other restrictive factors,various construction schemes are analyzed and compared.Finally,the incremental launching construction of arch and beam by integral walking is adopted.Ningbo Xindian Bridge is a rare bridge with the incremental launching construction of arch and beam by integral walking in China,is also the first bridge in Ningbo to adopt this construction technology,and is of great significance for bridge construction in Ningbo and even the whole country,which has certain reference significance for the bridges with the same type of construction method.
