【 摘 要 】

In this paper, the Qingping Slope station in Nanning is taken as the research object, in the light of seismic performance of underground station structure, considering the soil-structure dynamic interaction, using a finite element software, and based on reasonable simplification and simplification conditions, the three-dimensional model of the whole station which includes soil, station structure and pile foundation is established, then the seismic analysis is carried out and the dynamic response value of different transcendental probabilities and different seismic waves is obtained. Through analysis, it is found that the bending moment of the connection between the column and the roof and the floor of the station is larger; and for different seismic waves with the same peak value, the dynamic response of the station structure is obviously different, but the corresponding variation trends of the structure are consistent; because the constraints of the junction between the two ends of the tunnel are partly weaker than the middle, the bending moment of the column is larger; at the same time, it can be aware that maintaining the symmetry of the cross section is beneficial to the improvement of the seismic performance of the subway station structure. The research results can be provided to similar seismic analysis of underground engineering structure as useful reference and suggestions.
