摘要

A series of electro-osmosis experiments were conducted to explore the effect of voltage and temperature on the electro-osmosis properties of marine clay, including current, average consolidation degree, horizontal shrinkage, shear strength, water content, and anode corrosion. As shown for the resistivity of marine clay, the temperature increased when the electro-osmosis phenomenon occurred. From mechanical and electro-chemical point of view, this study explained the differences in the average consolidation degree and horizontal shrinkage under various experimental conditions. Although a voltage loss appeared due to the anode corrosion, the high voltage and temperature were still found beneficial for the reduction of the soil water content and the increase of shear strength. Furthermore, the electro-osmosis effect at high voltage included the contribution of joule heating. (C) 2017 Elsevier B.V. All rights reserved.
