Numerical Simulation of Electro-Osmotic Consolidation: Case Study
Electro-osmotic consolidation is an effective technique for soft soil improvement. In this study, a multi-field coupling numerical model for electro-osmotic consolidation was proposed to simulate the dewatering and consolidation process of soft soils. Seepage, electrical, and stress and strain fields were considered and the boundary conditions could be adequately simulated. Two cases were studied and compared with the numerical results to verify the effectiveness of the numerical model. The numerical results showed good agreement with the field measurements. The intermittent current and polarity reversal conditions were simulated and exhibited significant influence on the development of settlement. The surface settlement could be more uniform with the application of polarity reversal method. The complex field conditions can be simulated, and the electro-osmotic consolidation process can be predicted by means of the proposed numerical model.
