Abstract

Abstract

One-dimensional electroosmotic laboratory test was conducted in saturated soft clay under one dimensional electroosmotic consolidation test device, by monitoring current, voltage, potentials, the amount of drainage in the process of electroosmosis, and initial and final moisture content and shear strength, electrical permeability coefficient, electric migration coefficient, energy consumption coefficient were used to study electroosmotic drainage condition under the way of different power output.The test results showed that compared to stabilized output way of voltage, the cumulative amount of drainage was smaller and drainage rate was more slowly, change amplitude of effective potential utilization rate was slight, electric coefficient of permeability and electric migration coefficient decay were faster, and the overall decline value of the moisture content and normalized shear strength were slightly larger in the mode of the voltage and current.Compared to the mode of constant-current output, cumulative displacement was larger and drainage rate was faster, change amplitude of effective potential utilization rate was small, electric coefficient of permeability and electric migration coefficient attenuation were more slowly, and the overall decline value of the moisture content and normalized shear strength were larger in the mode of current and voltage.By contrasting to energy consumption coefficient under the different way of hybrid power output, drawing the electroosmosis condition in the mode of current and voltage was more economic and reasonable.
