Comparing the relative merits of dynamic compaction, rapid impact compaction and impact rolling

Abstract

This paper reviews compaction by dynamic means and discusses factors that influence the effectiveness of the following techniques: Dynamic Compaction, Rapid Impact Compaction and Impact Rolling, all of which have their particular application in ground engineering. Case study examples covering a wide range of projects and soil conditions, are included. The improvement depths for each of these dynamic ground improvement techniques are explored, with the results from the case studies compared with published information to help the reader make informed choices given similar soil conditions. Case studies that report the measured magnitude of ground vibrations are also presented to assist with the assessment of the potential source of nuisance to people or damage to surrounding structures.
