000015597 520__ $$2eng$$aRailway tracks, which reduce the ground vibration, are necessary if the trains are passing near to building. Today the reduction effect of railway tracks is often determined by the complex (time domain) simulation of the passage of a complete train. This method of evaluating the reduction is very time consuming and the results include some arbitrary scatter. It is worth to look for simpler methods which yield clearer results in shorter time. This contribution presents the combined finite-element boundary-element method as a detailed method for the track-soil interaction and, on the other hand, some possible simplifications. One important idea for the reduction assessment is to split the reduction in a vehicle-track interaction part and a track transfer part. The track transfer is not influenced by the vehicle and by single axle loads and it can be calculated as a homogeneous problem along the track. The reduction of some tracks (for example of floating slab tracks) can be dominated by this track transfer function whereas other tracks (for example tracks with soft rail pads) are completely determined by the vehicle-track-interaction part. The different force transfer functions and the ground vibration ratios of tracks with elastic rail pads or elastic sleeper pads are shown as a result of the FEBEM model under a fixed harmonic axle load. The force transfer proves to be a useful quantity for to assess the vibration reduction of railway tracks.
