摘　　要：钢管混凝土系杆拱桥是我国近年来桥梁发展史上的一种新颖结构,具有自重轻、承载大、抗变形能力强的优点,在现代桥梁中处于有利的竞争地位。本文以宁波慈城大桥为依托,对该桥施工过程进行了分析,并采取必要的施工监控手段,使整个桥梁施工过程中受力和变形都处于理想状态中。Tied concrete- filled steel tubular （CFST） arch bridge is a sort of novelty structure in our country bridge developmental history in recently years. It has the merits of light deadweight, great beating capacity and strong distortion - resistant capacity, which occupies a competitive position in the field of modern bridges. On the basis of Ningbo Cicheng Bridge whole construction course, analysis has been made on the construction course, and necessary construction supervision instrument has been adopted to make the bridge stress, therefore distortion are perfect in the whole construction course.
