SOIL IMPROVEMENT OF RECLAIMED LAND AND WEAK FOUNDATIONS BY VIBROFLOTATION

    Abstract:  It was often noticed by engineers that a significant but unintentional improvement in the soil was obtained in loose cohesionless layers when driving or vibrating casings during the construction of pile foundations. Consequently, compaction using vibratory probes with v...
