钢筋混凝土桁架拱桥,十多年来为我国华东地区广泛采用的新型式。实践证明:这种桥型取得了较好的经济效果,用料省,造价低,工期短,地基要求低。为了便于推广钢筋混凝土桁架拱桥,同济大学与交通部规划设计院共同主编桁架拱桥设计图,该设计图总结了近年国内的桁架 Reinforced concrete truss arch bridge, more than 10 years for the extensive use of East China new type. Practice has proved that: This bridge has achieved good economic results, materials and materials, low cost, short duration, low foundation requirements. In order to facilitate the promotion of reinforced concrete truss arch bridge, Tongji University and the Ministry of Communications Planning and Design Institute co-editor truss arch bridge design, the design summary of the domestic truss in recent years
