Grossversuche zur Entwicklung eines Qualitaets-sicherungssystems fuer die Ruetteldruckverdichtung

摘要

Deep vibratory compaction is used since approximately 60 years to densify cohesionless soil down to maximal 40 m depth. Until now no reliable method exists to verify the compaction success during vibration. The achieved compaction can only be estimated afterwards by penetration tests. In this paper the main results of full-scale tests for developing the new monitoring and quality control system "Bauer-RDV-online" are presented, which indicates the compaction success during vibration.
