摘　　要：某大型站房结构采用了逆作法施工方案,即先施工屋顶钢结构,然后再施工下部轨道梁、落客平台及高架层结构。为了研究逆作法施工和后期预应力混凝土梁张拉对屋顶预应力钢结构的影响,建立整体模型,按照实际逆作法施工顺序进行了施工模拟计算,并与一次加载模型结果进行了对比分析,从而确保了结构的成型状态与设计相符。The main building of a railroad station is built with reverse construction. The steel structures of roof are constructed first, and then the rail beams, drop-off platform and overhead floor. In order to investigate the impact on the prestressed steel structures of the roof for the reverse construction and prestress tension of the concreet beams, the integral model is built, and construction simulation is conducted, and the results are compared with those of one time loading simulation, the structural shape conforms to design shape.
