五跨连续中承式钢管系杆拱桥设计

On design of five-span continuity semi-supported steel pipe tie bar arch bridge

以临汾市鼓楼西汾河大桥主桥30 m+80 m+105 m+80 m+30 m为例,简要介绍了五跨连续中承式钢管混凝土系杆拱桥的结构设计与施工特点,为同类长系杆连续拱桥的设计与施工积累了经验。

Taking main bridge,（30＋80＋105＋80＋30） meter,of Fen river Bridge on Gulouxi of Linfen,the paper introduces the structural design and engineering characteristics of five-span continuity semi-supported steel pipe tie bar arch bridge,so as to accumulate experience for the design and construction of similar tie bar continuous arch bridges.
