摘　　要：武汉火车站雨棚结构由于跨度较大,施工的先后顺序和施工过程中临时支撑的设置对结构施工过程中的稳定性和施工结束时的结构位移、构件内力有较大影响。结合施工条件,设计了一套完整的施工方案,并采用有限元软件ANSYS对该施工方案进行了模拟计算分析,证实了该施工方案的可行性与可靠性。Because of the long-span for the structure of Wuhan railway station, the sequence of construction and the setting of temporary supports during construction process have important influence on the stability of the structure during construction and the final displacement and member internal force of the structure. According to the construction condition, a complete construction plan is designed, which is simulated with finite element programme and proved its feasible and reliable.
