Project Details

RDVK Vibrocontroll


The research project RDVK-Vibrocontrol is a collaborative effort between the Institute of Geotechnics at the TU Vienna, the Keller Grundbau GmbH, the VCE Vienna Consulting Engineers ZT GmbH, and the Unit of Applied Mechanics at the University of Innsbruck. This research activity is financially supported by the Austrian Research Promotion Agency, in the scope of the funding programme Bridge 1. The concept of this research project is highly based on the outcomes of the research project "Dynamic Compaction with Deep Vibrators". Large-scale experimental tests and numerical simulations are performed to develop the scientific basis of a work-integrated compaction control system for deep vibro compaction. Compaction tests are performed using a deep vibrator in non-cohesive soil, while its motion behaviour and essential process parameters are recorded. The experiments aim the identification of the motion behaviour of the deep vibrator in the dynamic vibrator-soil interaction system, in cohesionless soils. Additionally, the formulation of correlations between the compaction success and the motion behaviour of the deep vibrator as well as relevant process parameters is obtained. The results of the preliminary project and the expected results of this research project serve the identification a general indicator for the compaction state during deep vibro compaction and consequently a definition of a VCC-value (vibrator integrated compaction control).
