Abstract

Abstract

According to a lot of laboratory tests,generally master the law of level electro-osmotic drainage of the unsaturated cohesive soil with different electric potential gradient. Do some electro-osmosis curve analysis about the aspects of electro-osmosis displacement, drainage rate, soil resistance, coefficient of permeability of electricity, energy consumption and energy dissipation coefficient. The theoretical basis about electro-osmosis method for the future of the actual operation is given according to the termination conditions of electro-osmotic drainage determined by the analysis approximately. The results show that soil resistance increases and electric current decreases with the increase of conduction time. It leads the decrease of the electro-osmotic drainage rate. Electricity can be stopped in the end of electro osmosis for reasons of energy saving. It benefits electro-osmotic drainage and saves energy.
