Abstract:  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.
