摘要
桁式组合拱桥是我国首创的一种兼有拱、梁特点的新型桥梁,用钢人字桅杆悬拼施工。本文简要论述了该桥型的结构特点,并对正在设计中的主跨330m的桁式组合拱桥桥型方案的选择、结构设计计算和悬臂拼装工艺等作了扼要介绍。
The combinated arch bridge with truss pattern is a new type bridge origi-nated by China which has both the arch and beam features. It can be con-structed by cantilever assemblage method with a steel truss-mast. This paperbriefly discusses the structure peculiarity of the new type bridge schemes andintroduces the comparing project of the Jiangjiehe bridge in Guizhou Provincewith 330 meters main span combinated arch bridge with truss pattern; theoptimal design and computation of the structure as well as the cantilever as-semblage technique.
