摘　　要：拱桥具有特殊的线条美感,拱桥在城市桥梁中占有很大的比重,跨域能力及外观效果均能满足城市景观的需要。上承式拱桥的特点是拱肋决定拱上建筑,从结构受力安全和结构线形两方面均需要过程控制,施工监控是必不可少的一项内容,通过施工前模拟,将桥梁施工过程中的各种荷载、结构内力、后期横载充分考虑进行分析计算,提供相应的施工数据,施工过程中通过对坐标、高程、应力、应变的测量进行监控,保证施工过程安全并最终满足设计要求。The arch bridge has the particular line beauty. The arch bridge occupies a large proportion of urban bridges. Its spanning ability and its appearance effect all satisfy the demand of urban landscape. The characteristic ofdeck arch bridge is the arch rib to determine the architecture on arch. And itsprocesscontrol isrequired from two aspects of the structural stress safety and the structural alignment. The construction monitor is an essential content.Accordingtothesimulationbeforeconstruction,variousloads,structuralinnerforcesandlatehorizontalloadsinthe constructionofbridgearefullyconsidered toanalyzeand calculate. Therelativeconstruction dataareprovided. The measurement of coordinate, elevation, stress and strain is monitored in the construction so as to guarantee the safety of constructionprocess and finallysatisfy the designre quirements.
