Vibrations induced by tunnel boring machines in urban areas: Dataset of synchronized in-situ measurements inside the shield and on the surface

Abstract

In order to evaluate the potential impact of the shallow tunnel excavation by a tunnel boring machine (TBM) in urban areas, the authors present original in-situ measurements of vibrations inside the TBM and simultaneously on the surface. Four experimental campaigns were carried out on French tunnelling or micro-tunnelling projects, whose geotechnical contexts vary from hard rock to clayey sands. Each campaign is divided into two steps: (i) before excavation, measurements on the surface under mechanic ambient noise, and (ii) during excavation, measurements on the surface and inside the TBM. The present dataset consists in collecting, for each campaign, the time histories of all the synchronised sensors. They could be use particularly to estimate the vibration levels at different locations, and to analyse the frequency domain of the different signals.
