Abstract

Electro-osmosis is an effective method for accelerating the consolidation of soft soils while it has not been widely used in practice because of its high electric energy consumption. With development of renewable solar energy, the solar energy is used in electro-osmosis method and the solar electro-osmosis technology has been proposed. This paper presents the performance of solar electro-osmosis method to improve the consolidation of soft clay based on the laboratory experiment, including the electric current and voltage, electric potential, water discharge, water content, shear strength. The energy consumption and carbon emission have also been discussed based on the measured data. The measured results show that both electric current and voltage in solar electro-osmosis are not stable and vary periodically in day time; the solar electro-osmosis can accelerate consolidation of soft clay effectively and the solar electro-osmosis technology has a well drainage efficiency and environmental benefits.
