Vibroflotation Control of Sandy Soils using DMT and CPTU

Abstract

Vibroflotation is a typical improvement method for the cohesionless deposits of high thickness. The compaction method was applied to densify sandy deposits in Gdynia Port. Compaction control was verified with CPTU and DMT tests. Some examples of interpretation of soundings in pre-treated and compacted sands are shown. The classification diagrams are given for pre-treated and compacted sand. The stress history of the deposits is analysed. For a given relative density a considerable increase of lateral stress index was recorded after compaction. Some acceptance criteria for compaction control are discussed. The sensibility of CPTU and DMT methods to compaction control is analysed.
