摘要
通过对苏州工业区北环快速路东延二期新建高架桥上跨现有的娄跨大桥现浇箱梁施工方案的介绍,对上跨既有桥梁现浇箱梁支架设计进行了探讨,并对跨线桥现浇箱梁支架体系中的中间支墩设置、支架联接等关键环节、关键工序提出较为可行的控制措施。
This paper introduced construction scheme of cast-in-place box girder for the new viaduct of East Extension Phase 2 on North loop expressway in Suzhou Industrial Park, which is crossing over the existing Loukua bridge. It discussed bracket design of cast-in-Place box girder crossing over existing bridge. Feasible control measures of key points and the key processes including intermediate pier setting and the bracket connection in cast-in-place box girder bracket system of flyover were put forward.
