Consolidation of Dredged Sediments in a Confined Disposal Facility: Hydraulic Conductivity Constitutive Relations
When large strains are expected, such as for dredged sediments in confined disposal facilities, models that take into account constitutive relations for compressibility and hydraulic conductivity are required to study consolidation processes. A study has been carried out to design the filling and consolidation phases of a confined disposal facility for dredged marine sediments. The possibility to determine consolidation constitutive laws has been investigated using common incremental loading oedometer tests instead of more suitable but timeconsuming tests. The void ratio-hydraulic conductivity domain determined by oedometer test results has been compared with direct measurements at different void ratios. The results show a low trustworthy of this approach.
