This compaction method includes densification of loose sands by means of shear deformation processes imparted by horizontal vibrations of vibrator probe at the required soil depth. A cylindrical stay-tube and vibrator probe assembly are numerically modelled in the centre of cylindrical sand domain of 40 m depth based on the CEL approach. At the beginning of the deep vibration compaction simulation process the vibrator is simulated wished in place at a penetration depth of 20 m. The compaction process between 20 to 10 m depth, is modelled based on the pilgrim step method similar to the compaction procedure followed on field. A hypoplastic constitutive model is used to characterize the stress-strain behaviour of the sand. The effect of saturation of sand layer, shape of the vibrator and spacing of the compaction points on extent and degree of compaction is studied.enCELCompactionHypoplasticSandVibrocompactionIngenieurwissenschaftenConference PaperConference Paper
