Abstract: Baijiahu Metro station is constructed before the developing of the above Fenghuanggang surface buildings. Therefore, the designer of the Metro station must preserve conditions for the future developing of Fenghuanggang surface buildings. The stressing process of the structure of the Metro station under different working conditions are numerically simulated by means of finite differential software FLAC 3D. The displacement characteristics of the Metro station and the ground, the stress at the beam column node of the Metro station and the mechanical characteristics of the uplift piles under different working conditions are obtained. Optimum construction measures and advices are proposed on basis of the analysis results.
