Dynamic Compaction
Dynamic Compaction
(OP)
Greetings
I was wondering if someone could recommend a good text or publication for designing with dynamic compaction. Specifically, I was looking for some case histories or design guidelines for the drop height, weight and spacing.
I am aware of some of the problems such as those associated with silts/clays and excessive pore pressures.
Thanks for the assistance

Cone b',
Dynamic compaction essentially converts the potential energy of the hammer into the compactive force for the soil
The correlation is as follws
WH = D2 i.e D squared, W = weight of hammer, H height of fall and D is depth of influence densification.
There are issues of adjacent facilities etc hence its limited use, to be used with caution in built up area – potential liaibility claims.
hammer weights may be up to 30Tons at heights of +20m
Normally used for cohesionless soils and landfills
The issues are
type of soil in consideration
depth of planned excavation
required bearing capacities
spacing of compacting bulbs,cones
evaluation of other soil improveemnt techniques
It's not widely used in my area though
