The installation of inner concrete reinforcement lining within the damaged lining of existing tunnels that are still in service, will be one of the methods for extending the design life, the gradual deterioration of the structures and they require on-going maintenance. However, their reinforcement mechanism has not yet been clarified and they rational design methology has not yet been established.
In this paper, the load-carrying capacity and the failure behavior, that were obtained and observed by the carrying test of the full-scale specimens for real tunnel, are shown in case of inner concrete reinforcement lining. And a couple of notes regarding reinforcement mechanism of those reinforcements are discussed.
