| Abstract | A numerical model is developed to predict vibrations and re-radiated noise in buildings from excitation due to metro trains in tunnels. The three-dimensional dynamic tunnel-soil interaction problem is solved with a subdomain formulation, using a finite element formulation for the tunnel and a boundary element method for the soil. The periodicity of the geometry is exploited using the Floquet transform, limiting the discretization to a single bounded reference cell. The responses of two different types of tunnel due to a harmonic load on the tunnel invert are compared, both in the frequency-wavenumber and spatial domains. The tunnel of the line RER B of RATP in the Cite Universitaire in Paris is a shallow cut-and-cover masonry tunnel embedded in layers of sand. The tunnel of the Bakerloo line of London Underground in Regent’s Park is a deep cut-and-cover tunnel with a cast iron lining embedded in London clay. |
