A series of shaking table tests were carried out to investigate the seismic response characteristics of a multi-story subway station. Dynamic responses, including accelerations of the soils and the underground structure, layer drift, dynamic earth pressure, and lateral deformation of soils were recorded and analyzed. Several seismic characteristics of multi-story subway station structures are figured out. It is found that in addition to the racking deformation, the rotation vibration is observed for the multi-story subway station subjected to acceleration waves. From the viewpoint of frequency, the low-frequency component and high-frequency component of the acceleration response of the subway station represent the translation and rotation component of the multi-story subway structure, respectively. In addition, the rotation vibration of the deep-depth structure leads to the local squeezing and detachment from the surrounding soils alternately at both top and bottom ends of the sidewalls. This results in the hump-shaped distribution of dynamic earth pressure. The racking deformation of the multi-story subway station has a linear relationship with the dynamic earth pressure at a certain area along the sidewall, where the top of hump-shaped distribution of dynamic earth pressure is.

进行了一系列振动台测试，以研究多层地铁站的地震响应特征。记录并分析了动态响应，包括土壤和地下结构的加速度，层漂移，动态土压力和土壤的横向变形。指出了多层地铁车站结构的几个地震特征。结果发现，除了层架变形之外，多层地铁站还受到加速波的旋转振动。从频率的角度来看，地铁站加速度响应的低频分量和高频分量分别代表多层地铁结构的平移和旋转分量。此外，深层结构的旋转振动在侧壁的顶端和底端交替地导致局部挤压和与周围土壤的分离。这导致了动态土压力的驼峰状分布。多层地铁车站的货架变形与沿侧壁的一定区域处的动态土压力呈线性关系，该区域是驼峰状的动态土压力分布的顶部。
