A dynamical model of a double-deck circular tunnel embedded in a full-space

This thesis presents a three-dimensional dynamic model of a double-deck circular tunnel embedded in a full-space. The model uses the receptance method to obtain the response of the complete structure from the response of its parts. The considered subsystems are the interior floor and the tunnel-soil...

The model uses the receptance method to obtain the response of the complete structure from the response of its parts.

The classical thin plate theory is considered to represent the behaviour of the first and the Pipe in Pipe model is chosen to describe the second. Because the complete model is assumed to be geometrically invariant in the train circulation direction, the coupling of both systems is performed in the wavenumber-frequency domain. After the model formulation, some important issues about its numerical computation are detailed and the obtained results are discussed. The response of a double-deck tunnel to a dynamic and to a quasistatic excitation is compared to the response obtained for a simple tunnel.
