Abstract

This case history describes the densification of hydraulic fills by vibroflotation method. A total of 1, 034, 000 m 3 of hydraulic fills covering an area of 181, 000 m 2 are densified to a minimum relative density of 70%. Soil classification for initial state of the hydraulic fills is investigated based on CPTU test results. The physical properties of the hydraulic fills and the details of the densification works are presented and the results of the quality control tests are discussed. Compaction energy and corresponding increase in cone resistance, Δq c are examined for different type of soil and results are presented.
