Comprising 97 papers on Geotechnical & environmental aspects (Pile-soil modelling, vibrations); Dynamic testing (Equipment & data acquisition systems); Performance during installation (Driving equipment, hammer-pile-soil system); Reliability of predictions (Theory versus experiment and simulation). Each part starts with a lecture by invited keynote speakers; followed by a general report on the papers. New themes considered are environmental aspects related to vibration and noise & the reliability of predictions emphasizing the validation of theoretical methods & practical experience.
