Abstract
Repeated dropping of a heavy weight onto the ground surface is one of the simplest and most basic methods of ground improvement. The major use of the method in the UK has been to compact loose, partially saturated soil or fill - dynamic compaction. The ground is compacted in a predetermined pattern by repeated impacts of a large mass. The weight may be dropped in free fall from a large crane or within guides, or as a variation of this technique, the rapid impact compactor, where a hydraulic piling hammer impacts an articulated foot that remains in contact with the ground surface. This report contains a technical specification for ground treatment using dynamic compaction by either the falling-weight or the rapid impact method. Notes for guidance and information explain and clarify the particular clauses of the specification.
