Densification of domestic waste fills by dynamic compaction

Abstract

Dynamic compaction of solid waste is important in landfill operations because increasing the density of the material increases the storage capacity of the landfill. Differential settlements are also reduced, which is important for the integrity of the cover system. In this paper, a case study concerning a waste disposal site situated at Maldegem, Belgium, is presented. It is shown that young landfills behave differently from old landfills. This phenomenon results from the biodegradation of the wastes. Moreover, it is shown that the depth of influence, the crater depth, the enforced settlement, and the peak particle velocity are affected by this ageing process. Key words: dynamic compaction, landfills, SASW method, waste.
