Numerical modelling of ground-borne noise and vibrations in buildings induced by pile driving

Pile driving is one of the most methods used for foundations constructions when dealing with shallow soil layers with low bearing capacity. This pile installation in urban environments requires significant level of knowledge from the scientific and technical communities about the phenomena of generation and propagation of vibrations with emphasis on its interference in nearby buildings and the consequent nuisance of their occupants. In this context, a numerical model to predict vibrations and re-radiated noise in buildings induced by pile driving is presented. The model is based in a sub-structuring approach, where the whole propagation media is considered, from the vibration source to the receiver. An application example is presented, where the vibrations and re-radiated noise levels inside the building due to pile driving are assessed, clearly showing the pertinence of this work.
