Under the present international energy hype, it is necessary to develop new and/or renewable energy sources, which substitute for fossil energies. Among new and renewable energy sources, the geothermal energy is not only inexhaustible but also eco-friendly. In this research, a new geothermal energy source from tunnel wall is studied by conducting a preliminary laboratory experiments to measure thermal properties of shotcrete and concrete lining and by constructing test bed for in-situ testing.
