- The installation of piles and sheet piles in the vicinity of existing foundations requires the engineer to predict the environmental impact on nearby structures and buildings. In the presented case study an extension of Karlstad theatre was planned, the theatre and surrounding buildings are founded on loose geological deposits close to the river delta of Klarälven. The uncertainty in predicting the environmental impact on the theatre and adjacent buildings led to the decision of performing a trial sheet piling using vibratory driving. The generated ground vibrations as well as the settlement of the ground surface were measured. The results of the measurements showed that large settlements occurred in the loose sand layer. It was also observed that the horizontal vibrations were larger than the vertical vibrations close to the driven sheet piles. From the field study it was concluded that geotechnical conditions as well as distance from the source have large impact on the generated vibrations. A comparison between measured and predicted vibrations using empirical relations gave valuable insights for the development of future prediction models.
