    Abstract

    Cohesive sediment suspension deposition and consolidation mechanisms are mainly related to weight settlement and nonlinear consolidation processes. With the sediment settlement and suspension interface rate attenuation curves, sediment suspension settlement can be divided into different stages. The excessive pore pressure, void ratio, and saturated bulk density in depth all have nonlinear distributions. Consequently, settlement simulation and deposited layer tests are key in cohesive sediment suspension deposition and consolidation studies. This paper also proposes a new settlement column system recording the sediment interface settlement curves, the interface rate attenuation process, the excessive pore pressure, and the physical property distributions in a deposited sediment layer. Results from this study indicate that the newly developed system can effectively simulate cohesive sediment suspension deposition and consolidation in accordance with nonlinear consolidation characteristics.
