Tunnel beds are typically formed by massive concrete bodies. In the paper, a mechanically stabilized granular layer with a triaxial geogrid is considered as an alternative solution for tunnel beds. Experimental research was executed on a full scale model of the bed construction in the laboratory. Total settlements, resulting horizontal pressures on the walls and lateral deformations of the base of layers during static and dynamic loading with up to 2 million loading cycles were monitored and evaluated. The tests and results will be described and discussed in the paper. The construction of a mechanically stabilized granular bed derived on this basis can be presented as an innovative and effective solution for infrastructure tunnel projects.
