软弱土层中典型地铁车站结构的动力响应特征

omprehensive seismic analyses have been conducted on typical subway station structures in deep soft soils, in the city of Shanghai, through general-purpose finite element code Ansys. Features and properties of the dynamic responses of such a underground structure are studied, taking account of structural depth, structural style and input ground motions. Based on the numerical results, effects of the parameter sensitivities on subway station structures are discussed, as may be benefit to the improvement of seismic design level for underground traffic buildings.
