Very interesting research on Dynamic Ground Response during vibratory sheet pile driving. The paper was written by K. Rainer Massarsch, Carl Wersäll and Bengt H. Fellenius and published in the ASCE Journal on Geotechnical and Geoenvironmental Engineering. We are proud that this team has used Dieseko’s PVE 40VM Variable Moment Vibratory Hammer as a reliable machine that sets the standard in this research.
