现浇箱梁组合支架整体横移施工技术研究

Construction Technology Study on Overall Transverse Movement of Composite Bracket for Cast-in-place Box Girder

以新建上海至南通铁路站前二标段张家港高架站特大桥现浇箱梁施工为工程背景,针对多孔简支箱梁支架现浇的特点,从技术可行性和经济合理性角度出发,分析确定组合支架的布置方式,采用midas软件对组合支架进行了受力计算,研究制定组合支架整体横移的移运系统.这可为今后类似工程施工提供参考.

Taking the cast—in—place box girder construction of Zhan舀iagang elevated station special bridge in the first two bids of newly—built Shanghai-Nantong railway station as the background.and according to the characteristics of cast-in-situ bracket for the multi—hole simply—supported box girder,the paper determined the arrangement of the combined bracket from the perspective of technical feasibility and economic rationality,and calculated the force of composite bracket by using Midas software.Moreover,the paper studied and formulated the transporting system for moving transversely the composite bracket as a whole.It could provide a reference for the construction of similar projects in future.
