This study discusses how seismic isolation devices for center pillars of tunnels affect the moment and shear force distributions along side walls and upper/lower slabs as well as center pillars. The effects of seismic isolation are simply incorporated as flexible springs at the top end of the center pillars so that possible isolation effects can be taken into account in a simplified and comprehensive manner for the convenience of parametric study. The obtained results are useful for those who would like to choose appropriate devices for the seismic isolation of tunnels.
