This paper describes the fire resistance tests of full-scale thickness specimens in order to understand the fire resistance efficiency of SFRC lining for the ECL tunneling method. We compared the fire resistance efficiency of the SFRC lining and the RC segment, and clarified the effect of the steel fiber and the reinforcing bar. Rapid heating experiments of various concrete test pieces were done, and the SFRC lining and the RC segment which have full-scale thickness were experimented without fire proofing cover on the surfaces exposed to high temperature. The damage level of the lining surface due to explosive spalling, the temperature distribution in each lining, the residual compressive strength of the concrete and the crack situations etc. were compared.
