DYNAMIC COMPACTION OF RECENT EMBANKMENT AND COMPRESSIBLE SOIL. APPLICATION TO MARITIME STRUCTURES

LA CONSOLIDATION DYNAMIQUE DES REMBLAIS RECENTS ET SOLS COMPRESSIBLES - APPLICATION AUX OUVRAGES MARITIMES.

Dynamic compaction is characterized by the use of large scale energy: a mass weighting 8 to 20 tonnes hits the soil surface, failing free from 8 to 15m at a rate of 2 to 3 hits per minute. The temping programme is determined as a function of the nature of the materials. The experience acquired during a number of operations, shows that this technique, used originally for the compaction of highly pervious materials, was in fact most often applied to semi-impervious saturated soil such as silt and sandy clay. In the latter case, compaction is obtained through successive applications of tamping energy, with intermediary rest periods. The energy needed is calculated from laboratory results (dynamic oedometer).
