摘要
准池铁路前窑子水库大桥(58+3×96+58)m有砟轨道混凝土连续梁,原设计采用挂篮悬臂施工,为实现准池铁路"先通后善、临管运营"的目标,改为支架现浇法施工,施工工期节省了一半时间。详细介绍梁部结构的设计概况、主要设计参数、构造细节、计算方法,以及设计中需要注意的问题。
In the original design for the ( 58 + 3 × 96 + 58 ) -m concrete continuous girder with ballasted track of Qianyaozi Reservoir Bridge on Zhun-Chi Railway, the cantilever construction method with form traveler was adopted. Afterwards, in order to achieve the ideal goal of putting this bridge into operation as quickly as possible, the cast-in-place method with support frame was then employed, instead of the previous construction method, so that the construction period was finally shortened by half. This paper introduces the design overview of girder structure, the main design parameters, structural details, construction method and the issues to be noticed in design.
