A new seismic isolation technology ln which a slip easily occurs between a stracture and its peripheral soil or back-filling material has been developed. Such slip takes place by coating the outer surface of structure with a particular silicone paint of water emulsion type with kinetic friction coefficients as low as 0.15. In this paper, seismic design method of urban tunnels in consideration of slip is described first. Then, seismic isolation design is applied to an actual shield-driven tunnel. Seismic isolation design is conducted, focusing on the tunnel portion at connections with vertical shafts. In this design, authors propose the combined use of an isolation layer and segments coated with slipplng material, for the purpose of minirmzing cost and improving isolation effect. As a result, this technology is proven to be more effective and less expensive than the conventional measure.
