Abstract:

In this study, the surface settlement induced by shield TBM excavation is simulated by using finite differences code Flac-3D. The proposed three dimensional simulation procedure is taking into account the main features of slurry shield TBM. The line D subway project in Lyon is chosen to validate the numerical simulations. The comparison of the numerical simulation results with the in-situ measurements shows that the proposed 3D simulation is relevant, in particular in the adopted representation for the different operations achieved by the tunnel boring machine.
