摘　　要：结合京津客运专线悬臂浇筑连续梁的施工过程,介绍了主梁的整体线形及各节段间的接缝控制和桥面横向六面排水坡等平整度控制内容,对全桥合拢后桥面的平整度缺陷处理方法进行了阐述,对今后悬浇连续梁施工中的桥面平整度控制与处理有一定的借鉴作用。With the construction process of the project of the cantilever-cast continuous girder of the Beijing-Tianjin Inter-municipal Passengers oriented Railway as a practical example, the linearity control of the whole standing girder, the joint control of different sections, the level control of the tranverse draining slope, etc. , are introduced in the paper, with the methods to deal with errors in deck levelness after all the bridge sections meet each other presented, which may serve as a useful reference for the deck level control and treatment in other similar projects.
