VIBRATORY DENSIFICATION OF COHESIONLESS MEDIA

The results of a research project on vibratory densification of granular media are presented. The investigations are classified into two parts: assessment of variables involved in compaction of sands under vertical vibrations; and compaction of confined sand layers subjected to vertical vibrations. Two sands and three cohesionless media of different gradations and specific gravities were vibrated in four containers of different sizes and shapes. The results show that the effect of the size and shape of container on densification of sands is insignificant, but the peak acceleration plays a decisive role. The effect of inertial forces is studied for different materials. A silk cloth is interspersed between layers and the effect of confinement of sand on density at near zero surcharges is investigated.
