Electro-osmotic consolidation of soil with variable compressibility, hydraulic conductivity and electro-osmosis conductivity

A Simplified Analytical Approach for Coupled Injection Method of Colloidal Silica with Time Dependent Properties

Electro-osmosis in clayey soils and sediments, for purposes of clay consolidation, dewatering, or cleanup, and electro injection in porous media is widespread recent decades. It is experimentally found that the chemical properties of porous media especially PH change the characteristics of media. Electro-osmotic conductivity is a function of soil and grout material chemistry, altering with time...

Electro-osmotic consolidation: Laboratory tests and numerical simulation

Electro-osmotic consolidation is an attractive soil improvement technique for soft clay. A review of research and practical applications of electro-osmosis was performed. The achievements and major bottleneck of the current technique were briefly discussed, and the potential areas for scientific research and engineering application were proposed. A laboratory testing facility was developed for ...

Computer Erosion Modeling Considering Soil Hydraulic Conductivity

Improved computer models of erosion have been developed, considering soil hydraulic conductivity. The models deal with erosion of levees, dams and embankments due to overtopping. The simulations trace the formation of rills and gullies, beginning with initial overtopping and continuing to final breaching. Physical models performed at 1-g and high g using a geotechnical centrifuge have been used...
