【 摘 要 】

The investigation on the influences of electrolyte and flow shear on rheological properties of highly-concentrated cohesive sediment suspension is an important subject in the context of sediment transport dynamics. By means of experiment measurement and theoretical analysis, this project studies the influence of electrolyte (valence of cation and concentration) on the rigidity (or viscosity) and yield stress of highly-concentrated cohesive sediment suspension under a static condition, then discusses a possible explanation involved in the role which is played by electrolyte in determinations of rigidity and yield stress of the suspension considering the influences of all factors such as electrolyte condition, primary sediment concentration, median size and size distribution of sediment particle.
