Abstract

The sub-surface vibrator (13), suspended on a rod (11), has an unbalanced weight (15) rotating about a vertical axis. With a supply of water and/or air if appropriate, it is vibrated into the ground. It is drawn up in a series of stages. It is held vibrating in individual strata. Compaction is calculated from the vibration amplitude, taking into account stress-dependent ground parameters.
