Generalization of equation of soil filtration consolidation

Abstract

Generalization, which includes physical and chemical factors in the equation of soil filtration consolidation, has been proposed. The equation of continuity of soil liquid and solid phases is written using the total time derivative. This allows considering the process of filtration consolidation taking into account an arbitrary finite number of affecting factors. The authors have applied the classical theory method, but the investigation object - the equation of filtration consolidation - is new. The specific factors that have been considered in this study are: concentrations of chemicals in the liquid phase of the soil, mechanical and chemical suffusion, and temperature. A survey of experimental and theoretical dependences of the densities of soil phases on these factors has been performed. Thus backgrounds for further research of influence of various factors on the processes of soil consolidation (such as soil skeleton creep, salt transfer, heat transfer, chemical suffusion, mechanical suffusion, etc) have been obtained.
