摘　　要：随着时代的进步,钢结构桥梁得到了极大的发展,相比混凝土结构而言,钢结构加工及安装的精度要求更高,对于钢拱桥而言,拱肋首节安装的精度直接决定整个桥梁拱肋安装的精度,针对拱肋首节及钢混凝土结合段的安装设计出了一种安装支架,通过此支架对钢混凝土结合段拱肋进行精细化安装,保证了拱肋安装的精度,缩短了结合段安装时精度的调整时间,保障了施工安全,提高了桥梁整体施工质量。With the progress of the times,the steel structure bridge has been greatly developed,compared with the concrete structure,the steel structure machining and installation of higher accuracy requirements,for the steel arch bridge,the installation precision of the first sec-tion of arch rib directly determines the installation precision of the whole bridge arch rib,the precision of arch rib installation is ensured,the adjustment time of the precision is shortened,the construction safety is ensured,and the overall construction quality of the bridge is improved.
