Two-Dimensional Consolidation Theory of Vacuum Preloading Combined with Electroosmosis Considering the Distribution of Soil Voltage

  • SOIL MECHANICS

Soil Mechanics and Foundation Engineering Aims and scope

It is necessary to consider the influence of the actual soil voltage distribution when establishing the consolidation equation to more realistically reflect the soil consolidation conditions during the vacuum preloading and electroosmosis process. The distribution of the soil voltage is analyzed by integrating previous results with independent experimental findings. The equation for the dissipation of the excess pore water pressure and the soil consolidation equation are derived based on the proposed model with a closed anode and an open cathode, and the analytical solution is verified by a model test. The results show that the measured excess pore water pressure values coincide with the calculated values, thereby proving the rationality of the consolidation equation established in this paper.
