关于加快悬浇连续箱梁施工进度的措施

Measures to speed up the construction progress of continuous cantilever box girder

沅陵沅水大桥主桥下部结构与引桥已施工完成,剩余主桥上部结构与附属工程。尤其主桥上部为单箱双室箱梁结构,跨径达150m,采用悬浇施工,施工难度大,危险性高。本文对在人员与设备投入、资金保障、现场管理等方面可采取的相应措施进行了介绍,以期加快工程进度,并为类似工程提供参考。

The substructure and approach bridge of Yuanling Yuanshui bridge has been completed,but the remaining superstructure and ancillary works have not been completed yet. In particular,the upper part of the main bridge adopts a single-box double-chamber box girder structure with a span of 150 m. It is difficult and dangerous to use the cantilever cast construction. In order to speed up the project progress and to provide reference for similar projects,the corresponding measures to be taken in personnel,equipment investment,capital guarantee,site management,and so on are introduced.
