Abstract: Based on the phenomena of electric charge accumulation observed in the model experiments, an electro-osmosis theory named electric charge accumulation theory is brought out in this paper. By substituting the principle of current continuity with charge conservation, the differential equation of charge accumulation model is built. The analytic solution of the differential equation shows that: the spatial distribution of electric potential follows a superposition of linear and trigonometric function, and finally levels off to a linear distribution, which is hypothesized by Esrig; the decreasing of potential gradient follows a certain style of exponential function, and levels off to a constant; the decreasing styles of electric current and soil conductivity are approximatively accordant with those in energy level gradient theory. Finally, the electric charge accumulation theory is validated by some tested data.

Key words: electric charge accumulation, electro-osmosis, consolidation, drainage
