摘要
上海市嘉定区桃浦路蕴藻浜大桥主桥为66 m+136 m下承式两跨连续桁梁—桁拱组合钢结构,承重体系为由箱形或H形杆件组成的两片桁架,桥面由纵横梁体系及正交异性钢桥面板形成,杆件之间的连接均为焊接,主要介绍主桥结构设计与分析计算。
The main bridge of the Yunzaobang River Bridge on Taopu Road in Jiading District of Shanghai City is a composite structure of two-span continuous through steel truss girder truss arch bridge with span arrangement（66＋136） m.The bearing system is twin steel trusses composed of box or H member and the floor system is composed of girders,transverse beams and a steel orthotropic deck.All bars are welded.In this paper,the structure design and analysis of the main bridge are introduced.
