Analytical solution for axisymmetric electro-osmotic consolidation.

Electro-osmotic consolidation is a potential method for soil improvement. An axisymmetric electro-osmotic consolidation model with coupled horizontal and vertical seepage is proposed and the analytical solution is derived without the equal strain hypothesis, which was used in previous models. The proposed analytical model can predict the distribution of pore-water pressure in the radial direction, and comparison with previous analytical models indicates that the degree of consolidation is overestimated if the model is simplified from an axisymmetric model to a planar model. A design chart is developed to facilitate the evaluation of applying electro-osmotic consolidation for soil improvement. [ABSTRACT FROM AUTHOR]
