ABSTRACT
A new theory for electroosmotic consolidation is presented in this paper. The proposed theory overcomes the two shortcomings of Esrig theory. The energy analysis model for electroosmotic consolidation eliminates the assumption of linear distribution of electric field in Esrig theory, which was proved to be not accordance with the experiments. The model is applicable for both saturated and unsaturated soils. The parameter of energy density level in the model, which has the same dimension as stress, is a bridging parameter that links the effective stress built in the soil with the energy consumption for electroosmotic consolidation. A model test was carried out to verify the proposed theory and it has been proved that numerical simulation based on the proposed theory is able to predict the distribution of water content after electroosmotic consolidation.
