摘　　要：对澳氹第四条跨海大桥单柱墩盖梁抱箍法施工工艺流程及施工方法进行阐述与总结,并针对抱箍托架法面临大悬挑及托架下沉问题,利用CAD画图软件设计优化抱箍托架图,利用Midas Civil建立模型进行受力分析,得出各方面受力均满足要求。This article elaborates and summarizes the construction process and method of the single column pier cap beam and hoop method for the fourth cross sea bridge in Aodang. And for the problem of large overhang and bracket sinking faced by the hoop bracket method, CAD drawing software was used to design and optimize the hoop bracket diagram. A model was established by using Midas Civil for force analysis, and it was found that all aspects of the force met the requirements.
