摘　　要：在大跨度连续梁施工中,确保桥梁成桥的线形状态符合桥梁设计线形的要求,是保证桥梁处于合理的受力状态、桥梁运营的安全以及桥梁外观线形优美的关键。基于哈大铁路客运专线文官屯(60+100+60)m悬臂施工连续箱梁施工仿真的工程实例,对桥梁施工过程进行仿真分析计算,为确保桥梁线形与应力的合理提供理论计算依据。The proper bridge stress,the safe bridge service and the appealing bridge profile are specifically guaranteed by the appliance of the bridge profile with the design requirements during the construction of large-span continuous beam.This paper,with reference to the engineering practice of the construction simulation of continuous beam with cantilever(60+100+60)m at Wengantun on Harbin-Dalian Passenger Dedicated Line,conducts simulation analysis and calculation for the beam construction process and serves as the basis for theoretical calculation to ensure proper bridge profile and stress.
