Sedimentation–consolidation modeling with an interaction coefficient

This paper examines the use of an interaction coefficient to couple sedimentation and consolidation phenomena with the conventional finite strain consolidation theory. A specific continuous interaction function was implemented and the resulted model was examined. The model was found to able to capture proper sedimentation–consolidation features. It was also determined that the structural and maximum suspension void ratios are the major factors controlling the shape of the void ratio profile. The model was compared with experimental data and other numerical models and qualitatively good agreement was obtained.
