A tunnel-group metro station built in rock site is composed of a group of *** tunnels and their interconnections can show inconsistent responses during an *** study investigates the dynamic responses of such a metro station in a rock site,by shaking table *** lining structures of each tunnel and surrounding rock are modeled based on the similitude law;foam concrete and gypsum are used to model the ground-structure system,keeping relative stiffness consistent with that of the prototype.A series of harmonic waves are employed as excitations,input along the transverse and longitudinal direction of the shaking *** discrepant responses caused by the structural irregularities are revealed by measurement of acceleration and strain of the *** characteristics are identified by the transfer function method in white noise *** test results show that the acceleration response and strain response of the structure are controlled by the *** particular,the acceleration amplification effect at the opening section of the station hall is more significant than that at the standard section under transverse excitation;the amplification effect of the structural opening is insignificant under longitudinal excitation.
