This paper describes reduction effects on seismic stresses in the cross section of shield tunnels with the backfilling area filled with flexible materials. First of all, a tunnel and ground model were produced and then reduction effects on stresses by backfilling were confirmed as the result of pure ƒL�[ƒ��[ƒh�i‰p�j�F shield tunnels, seismic stresses, pure shear loading test, seismic response analysis, seismic isolation system ‹LŽ–‹æ•ª�F ˜a•¶˜_•¶�i“Š�e˜_•¶�j ‹æ•ª �@�@�@�@˜_•¶�W
