ABSTRACT: This
paper presents a case study of the extensive soil improvement work carried out
on a reclamation project on the shores of United Arab Emirates. The project
consisted an area of approximately 480,000 m2 for recreation
purposes. Following the dredging work, approximately 6.8 million cubic meters
underwent densification using the vibrocompaction method. The general aims of such analysis are to
investigate the effectiveness of vibrocompaction as a method of soil improvement
and appraise the selection of this method as the most appropriate soil
treatment technique necessary for the adequate densification
of the overall loose soil masses. The efficiency of the vibrocompaction technique to densify thick granular-based
soil formations of considerable thickness and the benefits obtained,
equated to other soil treatment methods, was
assessed through a comprehensive post quality control program including
field and laboratory post-compaction testing. Based on the analysis conducted it is concluded that soil strength of
the reclaimed materials achieved a
noteworthy improvement reaching comfortably the required degrees of densification.
