Abstract: The deep vibration compaction method is widely used for ground improvement of granular soils. The porosity of the soil is reduced and therefore liquefaction due to dynamic excitation is prohibited. The deep vibration com-pactor consists of an unbalanced mass inside a steel tube. The mass located inside the tube is rotating around the vertical axis of the compactor such that the compactor is oscillating during the compaction process. Therefore, the vibration energy is directly transferred from the tube into the surrounding soil. Numerical simulations of this pro-cess are performed using a coupled Eulerian-Lagrangian Method (CEL).
