随着我国公路交通的不断发展以及桥梁建设规模的不断扩大,采用贝雷梁托架进行现浇连续箱梁施工的方式广受青睐,主要因其利于提高工程的施工质量。本文结合永吉高速公路匝道现浇箱梁托架施工实例展开讨论,介绍了工程概况,分析了现浇连续箱梁部分的托架施工方案和相关设计计算,以期为类似施工积累有益的经验,提供一定参考。 With the continuous development of road traffic in our country and the continuous expansion of the bridge construction scale, the way of using Berea beam brackets for the construction of cast-in-place continuous box girders has been widely accepted. This is mainly due to the fact that it helps to improve the construction quality of the project. In this paper, the construction example of cast-in-place box girder on-ramp in Yongji Expressway is discussed. The general situation of the project, the construction plan of the bracket and the related design and calculation of the continuous box girder are analyzed in order to accumulate useful experience for similar construction.
