Experiment Probe on Micro-Electric Field Effects on Seepage in Micro Particle Clays
Using laboratory experiment method, the micro-electric field effect on seepage in micro particle clays is discussed in this paper. A series of micro-and mesoscopic parameters and seepage consolidation tests are conducted for the samples of micro particle clays with different ion concentrations in pore water or particle surface electric potentials. The test results show that an increase in particle surface electric potential or a decrease in ion concentration will result in the decrease of equivalent permeability coefficient, consolidation rate and consolidation displacement, revealing the existence of micro-electric field effect on seepage in micro particle clays.
