Its basic principle is to utilize the electrophoretic effect under the action of electric field to make the particles in the soil move in a directional way, thereby changing the physical properties of the soil and enhancing the mechanical properties of the soil. Electrodes are a crucial component in electro-osmosis, and the arrangement of electrodes has a significant impact on electro-osmosis. In this paper, a mid-term report on the experimental study of the effect of electrode arrangement on electro-osmosis is presented. Firstly, the experimental equipment, experimental plan and physical and mechanical characteristics of soil are summarized. Then, the results of electro-osmosis experiments under different electrode arrangements are introduced, including the effect of electro-osmosis, stress-strain state of soil, and pore water pressure strength of soil. The results show that the electrode arrangement has a significant impact on the electro-osmosis effect and a reasonable electrode arrangement can significantly improve the mechanical properties of the soil. At the same time, there are differences in the electro-osmosis effect under different arrangement forms, and reasonable arrangement should be made according to different situations. Finally, the research contents of this midterm report are summarized, and prospects for future research work are proposed.
