摘要
武汉市江汉三桥主桥系单孔净跨为 2 80 .0m下承式钢管混凝土桁架系杆无铰拱桥 ,桥型新颖、结构复杂 ,技术含量高、施工难度大 ,施工中采用了一系列新工艺、新方法。简要介绍江汉三桥主跨钢管混凝土拱桥的钢管拱桁架节段吊装与混凝土泵送顶升施工工艺。该工艺取得了圆满成功和较好经济效益 。
The main span of the Third Jianghan Bridge is one-span of 280 m concrete-filled steel tube through tied-trussed-arch bridge. It is a bridge of new-type, with complex structure and high technics. The new technology and methods used in the lifting and erection of arch ribs, concrete-pumping and jacking-up of the CFST-trussed-arch bridge are presented in this paper.
