Assessment of Consolidation Behavior of Golden Horn Marine Dredged Material

Abstract

ABSTRACT Polluted sea bottom sediments from Golden Horn in Istanbul have been dredged and stored on land at a disposal site. Reclamation of the disposal site was highly dependent on prediction of self-weight consolidation behavior of the dredged material, which is analyzed numerically using software which employs a nonlinear finite strain solution algorithm (Fox and Berles Citation1997). The material parameters needed for the numerical model are determined using a seepage-induced consolidation testing system and prediction of the numerical model is tested against experimental observations in a slurry consolidation model tank. The numerical modeling of the field behavior at the disposal site could be successfully accomplished using sediment property data from the seepage-induced consolidation test.

Their support is greatly appreciated. The authors also extend their thanks to Prof. Patrick J. Fox, Ohio State University, who provided the computer code CS2 and to Prof. Dobroslav Znidarcic, University of Colorado, who encouraged them to utilize the seepage-induced testing system and provided the supporting documents.
