Objective
MetaTunnels redefines seismic protection of shallow-to-deep tunnels by introducing a new paradigm: a Resonant Metamaterial Lining (RML) that cloaks underground infrastructures from seismic motion. Replacing conventional lining, the RML is a 3D auxetic lattice where each node integrates a frequency-tuned multiaxial resonator. This double-scale architecture ensures high static performance while filtering out seismic energy across the frequency bands of shear, compressional and surface waves, enabling superior control of tunnel deformation.
MetaTunnels will establish and optimise the RML topology and mechanics through a scalable analytical-numerical workflow. The RML behaviour will be modelled via homogenisation based on a thermodynamic framework able to capture the roto-translational dynamics of the multiscale response, from the resonators to the auxetic lattice. The theoretical framework will yield an energy-consistent macroelement to be integrated into quantum-assisted 3D simulations of soil-RML-tunnel multiphysics interaction. Accordingly, the RML will be optimised to achieve broadband seismic wave attenuation via quantum-enhanced genetic algorithms, balancing inertial and dissipative effects across the entire system. Comprehensive validation of the RML will involve 3D-printed reduced-scale prototypes and geotechnical centrifuge tests on strategic underground facilities.
By harnessing the synergy of underground infrastructure vision, seismic metamaterials and quantum computing, MetaTunnels will deliver a disruptive technology that transforms how the underground built environment withstands seismic events, drastically reducing seismic risk while enabling global dissemination.
