摘　　要：以宁德市寿宁县坪坑大桥拱桥缆索吊装施工过程监控为例,基于现场实测数据,利用桥梁分析软件Midas对施工过程监控进行仿真分析,重点探讨拱圈拱箱节段吊装合龙、桥面铺装完成及徐变10年后的计算分析结果,得出施工预拱度的合理建议值及正常使用极限状态的计算结论,成果将为保证拱桥成桥线形提供理论依据及更好地指导后续施工。The cable hoisting construction process monitoring of Pingkeng Arch Bridge in Ningde Shouning County was taken for instance. Based on field data, using the bridge analysis software Midas to make simulation analysis on construction process monitoring. Focusing on probing the arch box lifting together, the bridge deck completed and creep calculation results after 10 years. Then come to a reasonably recommended value of pre - camber and calculation conclusions of normal use of arch bridge under ultimate limit state. These will provide theoretical basis for ensuring arch ring＇ s shape and better guide the subsequent construction.
