The RIVAS FINAL CONFERENCE
“Vibration – Ways out of the annoyance”, was held in Brussels, on 21 November 2013

The main objective of this work package is to develop and to optimise railway infrastructure based vibration reduction technologies in the transmission path, either under or next to the track. In the frequency range of railway vibration, the top layer of soil plays an important role which is often neglected. It leads to a ‘cut-on frequency’ above which a steep rise in the vibration trans-mission spectrum occurs. In these studies, a key approach is therefore to take the layered ground structure into account or alter its effect to form barriers to propagation.
In particular the work package has the following objectives:
The overall deliverable of the WP will be a set of guidelines on the possible effectiveness of each of the mitigation measures studied in different sites. The guidelines will contain information on engineering design constraints, costs and other factors to form a ‘technology assessment’ of each mitigation method
