Settlement of Dredged and Contaminated Material Placement Areas. II: Primary Consolidation, Secondary Compression, and Desiccation of Dredged Fill Input Parameters

Abstract

This paper presents practical applications of PSDDF (Primary Consolidation, Secondary Compression, and Desiccation of Dredged Fill), which is described in a companion paper by the writers. In addition, consolidation and desiccation parameters for 27 dredged materials are presented from 20 U.S. Army Corps of Engineers placement areas to facilitate usage of PSDDF. The consolidation parameters of three cohesionless soils for sand capping and drainage and three compressible foundation materials are included to provide a PSDDF user with suitable parameters for these material types. To reduce the difficulty of obtaining the consolidation and desiccation parameters for dredged material, empirical correlations between the required parameters and soil index properties are presented.
