A case study on energy-based evaluation of deep vibro compaction method
A case study on energy-based evaluation of deep vibro compaction method
This case history describes a well-documented and recently completed project in the Caribbean consisting of densification of hydraulic fills by vibro compaction method. The results of compaction are discussed based on energy criteria. The project site covers approximately 13,500 m2 with an average depth of 9.5 m are densified to a minimum relative density of 65% against liquefaction. Soil classification for initial state of the hydraulic fills is investigated based on CPTU tests. Before the commencement of the works, vibro compaction parameter tests were carried out in 3 different test areas. The physical properties of the hydraulic fill and the details of the densification applications are presented. A comprehensive quality control program was pursued in the project. The successful execution of works illustrates the effectiveness of the selected method. In this study, the total amount of compaction energy transferred per unit volume of loose hydraulic fill, corresponding increase in cone resistance (qc), the grid spacing, the vibro compaction production time are presented for each type of soil and results are presented.
