摘　　要：拱结构作为一种优良的受力体系,在工业与民用建筑、公共建筑、桥梁工程中得到了广泛的应用,随着其跨度越来越大,施工难度也随之大幅度增加,其中预变形已经成为施工控制的重要手段,因此对拱结构的施工方法和预变形分析方法进行总结和研究,对拱结构的施工具有较好的借鉴意义。The paper indicates the arch structure is a better stress system, which has the extensive application in the industrial and civil build- ings, the public buildings and the bridge projects, illustrates the pre-deformation is the important measure for the construction control as its span tends to be larger and larger and the construction becomes more difficult, so it also sums up and researches the construction methods for the arch structure and the analysis methods for the pre-deformation, so it has better reference significance for the construction of the arch structure.

关 键 词：拱结构 施工方法 预变形
