Investigations and results concerning railway-induced ground-borne vibrations in Germany

摘要

Besides noise reduction, ground-borne vibrations induced by railways are another important environmental issue associated with the construction of new or the reconstruction of existing railway lines that had to be tackled during the last decade. Annoyance can occur, particularly for lines in urban areas at small distances to neighbouring houses or lines in shallow depth tunnels under buildings. The ground-borne vibrations can be perceived by the inhabitants via the floor vibrations, as well as via the air-borne noise radiated inside the building by the vibrating building structures (secondary noise).
