摘　　要：泰州市青年路北延工程主桥采用下承式系杆拱桥,主桥跨径为168m,主梁、主拱均采用钢结构。介绍了该桥结构设计,建立了三维空间有限元模型,对此成桥运营状态下结构受力进行了分析,结果表明该桥设计合理,结构在理论成桥状态下受力良好。The main bridge of Youth Road in Taizhou City adopts through tied arch bridge. The span of the main bridge is 168 m, and the main girder and arch are all made of steel structure. This paper introduces the structure design of the bridge and proposes a three-dimensional finite element model aimed to analysis the structural stress under the operation state of the completed bridge. The results indicate that the design of the bridge is reasonable and subsystems work well under theoretical completed bridge status.
