In earthquake-proof designing on shield tunnel, the accurate evaluation of the axial stiffness of the tunnel is extremely important. Because the shield tunnel lining consists of many tunnel segments with joints, bolts, and other fasteners, and the inner surface is protected with a secondary lining, evaluation of the stiffness is not simple.<br>Shearing experiments were carried out on the lining models with different types of isolation. It was found that the shearing characteristic of isolation could for the most part be expressed by Coulomb's criterion.<br>Further, axial seismic responses of the shield tunnel were analyzed with a new analytical model that allowed for isolation effects and was verified with experimental results. It confirmed the observations that the axial response could be reduced by the insertion of an isolation sheet between the primary and secondary linings.
