摘　　要：墩帽作为桥墩的主要组成部分,在桥墩的承重中起承上启下的作用。目前常规的高铁墩帽整体切除、重新浇筑混凝土方案存在施工效率低、成本高等问题。以南龙铁路洋丹仔大桥桥墩为研究对象,对其墩帽的施工进行研究,从施工过程中总结出较为完善的工艺条件,以期为类似工程的施工起到借鉴作用。As the main part of the pier cap,the pier cap plays a connecting role in the bearing of the pier. At present,the conventional high-speed railway pier cap overall removal and concrete reconstruction scheme has the problems of low construction efficiency and high cost. This paper takes yangdanzai bridge pier of Nanlong railway as the research object. Construction of pier cap was studied,and the relatively perfect process conditions from the construction process was summarized,in order to play a reference role for the construction of similar projects.
