Vibrations due to the passage of trains in tunnels propagate through the soil and produce vibrations and re-radiated noise in adjacent structures. Within the frame of the EC-Growth project CONVURT ("The control of vibration from underground railway traffic"), an efficient and modular numerical prediction tool is being developed to predict vibration and re-radiated noise in adjacent buildings from excitation due to metro trains in tunnels for both new-build and existing situations. The model will be validated by means of in situ experiments at the site of Cité Universitaire in Paris and at Regent's Park in London. The development of a coupled periodic finite element-boundary element method and the results obtained from the in-situ experiments conducted in Paris are described in the present paper.
