Prediction and control of vibrations due to pile driving and sheet pile vibration
P.H. Waarts & M.W. Bielefeld

Pile driving in urban areas often causes annoying vibrations. Sometimes, even the risk of structural damage due to vibrations exists. For a proper risk assessment regarding the potential damage due to pile driving vibrations, a prediction method for the vibration levels is necessary. This paper presents a theoretical method. The source model is based on the pile driving prediction program TNOWAVE and the transmission of waves through the soil based on a FEM model. The method is meant to be used in case a minimum of information of the subsoil is available. The type of pile and hammer and the results of a CPT-test are necessary to make a prediction of the vibration level. A case study is presented, showing the results of both predictions and measurements. Comparison of predicted and measured vibration levels, indicate reasonably good results, considering the small amount of information used.
