［摘要］广州新客站采用逆作法施工，首先施工屋顶钢结构，然后施工下部轨道梁和高架层，需要考虑下部结构后施工对屋顶结构的影响。建立了整体模型，按照实际逆作法方案进行施工模拟计算，分析了各施工阶段屋顶结构受力状态的变化。与一次加载模型和顺作法施工模拟计算的结果进行了对比，讨论了逆作法施工方案对结构设计的影响，为工程设计提供了依据。

Abstract:The New Guangzhou Railway Station is conducted in reversed order. The steel roof structures are conducted first, and then the rail beams and overhead floor. The influence on the lower structures to the roof structures should be considered. The integral models are built, and construction simulation is conducted, and then the changes of forces of the roof structure in every stage are analyzed. The results are compared with those of one-time loading simulation and normal order simulation. The influences of reversed construction sequence to structural design are discussed, and reliable suggestions are proposed to the project design.

Keywords:New Guangzhou Railway Station; construction in reversed order; construction simulation
