Measurements with VibroScan vibrator in Gotthard base tunnel
Vibration control is a vital factor for ensuring the safety of tunnels and overlying buildings. Following completion of the tunnel drive, a VibroScan vibrator was used to simulate the vibrations caused by trains in the tunnel and their effect on the overlying buildings. The sensitivity of the signal measurements was amplified by means of special MAPLE programming routines developed by Gruner. This paved the way for high-accuracy predictions and the optimization of protective measures.
