Ground vibrations due to pile and sheet pile driving - prediction models of today

摘要

As part of a construction work pile and sheet pile driving unavoidably generates vibrations. As of today construction works are often located in urban areas and along with society's increasing concern of environmental impact the need for vibration prediction prior to construction is of immediate interest This study presents a review of the prediction models existing today. For prediction of ground vibrations from pile and sheet pile driving there are roughly three different types of models, empirical models, theoretical models and engineering models. A prediction model should be reliable in all cases where it is meant to be used. It is also important that it is relatively easy to use and that the input data is easily obtained. This study concludes that, as of today, there is a lack of such a model. Today's models either lack in reliability or require great amounts of input data, knowledge and skills as well as time and money. The findings within this study constitute the initial part of an on-going research project at the division of Soil- and Rock Mechanics at the Royal Institute of Technology in cooperation with the Development Fund of the Swedish Construction Industry and NCC Construction Sweden.
