In order to study the seismic response of the tunnel vertical underneath station structure,a model of the small-interval tunnel vertical underneath signal-storey station in the silty clay was designed and manufactured.Using the numerical model verified by the shaking table test results,the stress,displacement,deformation and acceleration response laws of the underground crossing structure were studied by inputting seismic waves with different peak accelerations.The research results show that under the action of lateral earthquake,the asymmetrical tunnel crossing the station will affect the seismic response characteristics of the station,and the maximum values of stress,acceleration and deformation will deviate from the position of the center column;the inner stress of the station and tunnel is about 70%～80%of the outer;the center column of the station is still weak in earthquake resistance.
