The Effect of Dry Unit Weight in Hydrodynamic Dispersion of Clayey Soils

Baris Mahmutluoglu, Baki Bagriacik

Abstract: In this study, hydrodynamic dispersion is explained which is the combined effect of grain diffusion and dispersion of a soil. Dry unit weight of a soil is shown to be the most effective parameter in hydrodynamic dispersion. The results obtained by traditional consolidation tests are compared to the theoretically obtained counterparts. All of the aforementioned theoretical values are derived from the theory of hydrodynamic dispersion. Additionally, by considering the hydrodynamic dispersion of a soil during consolidation, time rates of pore water, settlements and compression of soil skeleton can also be considered in terms of hydrodynamic dispersion and so the viscous properties of soils are able to be investigated as well. It can also be pointed out that the obtained data can especially support the studies about slope stability problems of soils.
