Numerical Simulation Of Electro-Osomosis In Soft Clay

  • Conference paper
Advances in Environmental Geotechnics

Abstract

Electro-osmosis consolidation seems to be a potential technique for improvement of soft clay. The traditional electro-osmosis theory cannot provide satisfied solution since the hypothesis of constant parameters of mechanical and electrical properties of soils. In this paper, FEM software is developed to couple the Lapalace&s equation for electrical field with Biot&s consolidation equation, and the displacement of soil mass and pore-water pressure can be obtained during electro-osmosis process. The non-linear variety of hydraulic permeability of soil mass during consolidation is incorporated in the control equations. The boundary conditions for electrical field, seepage flow and displacement can be adequately simulated. The calculation results agree well with the monitoring data from analytical model. The software can predict the displacement behavior of soil mass and provide useful data for system design of electro-osmosis treatment.
