Installation by vibrodrivers of sheet and bearing piles generates periodic vibrations in the surrounding ground, which have been widely measured and reported. One of the possible consequential effects of these vibrations is ground settlement caused by the compaction of loose granular soils. Vibratory compaction settlement of a range of granular soils has been studied in the laboratory using a 150mm diameter Rowe cell, which allows sample preparation and control during vibrations equivalent to conditions in the field during vibrodriving. The cell containing the soil sample was mounted on an electromagnetic shaker and vibrated at amplitudes and frequencies appropriate for soils adjacent to vibrodrivers. The changes in sample height were recorded.
