Massarsch. K,R,, Wersäll, C. and Fellenius, B.H. Horizontal stress increase induced by deep vibratory compaction. ICE Geotechnical Engineering .

Compaction by vertically or horizontal oscillating probes increases not only the soil stiffness but also the horizontal effective stress. An important, but often neglected, consequence is that compaction also causes preloading of the soil. In this work, five case histories reported in the literature where different vibratory compaction methods were used (dynamic compaction, vibroflotation, VibroWing, TriStar and resonance compaction) were re-analysed.
