MODEL INVESTIGATIONS ON THE PROPAGATION OF STRUCTURE-BORNE-SOUND IN THE AREA OF SUBWAY TUNNELS

MODELLUNTERSUCHUNGEN ZUR AUSBREITUNG VON KOERPERSCHALL IN DER UMBEGUNG VON U-BAHNTUNNELN

The prediction and the control of structure-borne vibrations in subway railway systems are well known problems. The reported investigations were concerned with possibilities of using simple and practical model set-ups to give answers to these problems. The scale factor was 1:10. The results show that model experiments together with theoretical approximations can be acceptable tools for the determination of the mean structure-borne sound behavior of both subway tunnel itself and for the areas nerby the tunnel. In the cases where a receiver is relatively far away from the tunnel the model leads only to qualitative results, because of the increasing of inhomogeneities and frequency dependencies. Also the model setups are predictable only for simple structures of soil.
