摘　　要：结合哈大客运专线1-138 m钢箱叠拱桥施工方案的设计,运用Midas有限元计算软件,分析运梁车过梁和架桥机架设箱梁过程中临时桥面系、桥面板的受力特点,为最终施工方案的制定提供依据,计算表明施工方案切实可行。With reference to the design of construction program for 138 m steel box superimposed arch bridge on Harbin-Dalian Passenger Dedicated Line and the application of Midas finite element calculation software,this paper analyzes the stress conditions of the temporary bridge decking and the deck slab when the transport vehicle is getting across the bridge and box girder is being erected,which may serve as references to determine the final construction scheme.Calculations have justified the feasibility of the construction scheme.
