Abstract

The development of underground railways is driving demand for a better understanding of their impact on sensitive buildings, where the resulting ground-borne noise and vibration can cause disturbance to both occupants and equipment. This paper reports on a scenario that occurred in central London, where the new twin-tunnels of Crossrail were bored underneath some recording studios, causing concern over how the tunnels would affect the acoustic environment in the studios. Vibration in the studios building was therefore monitored throughout the construction period. Since Crossrail is yet to operate, the resulting data provides a unique opportunity to investigate the effect of new tunnels, acting as passive buried structures, on the existing vibration environment. The paper summarises the results of the initial data analysis, which indicates that the construction of the second Crossrail tunnel has led to an overall reduction in the vibration levels beneath the studios. Further analysis indicates that any seasonal variations in vibration levels over the measurement period are negligible, adding weight to the conclusion that the observed changes are a causal effect of the tunnel.
