Experimental Study on the Strengthening Effect of Cyclic and Progressive Electroosmosis

In view of the application plights of electroosmosis, a cyclic and progressive electroosmosis method (CPE) was proposed and verified using laboratory experiments. The electrifying mode and number of electrodes for CPE were evaluated by analysing the water discharge, current, shear strength, and water content of the soil after treatment. The results show that CPE can concentrate the water distributed in large areas to the predetermined electrode and improve the drainage efficiency of solely this electroosmosis method. After treatment, the shear strength and water content of the soil were significantly improved by CPE. Reducing the cyclic electrifying time and decreasing the number of electrodes appropriately was helpful in reducing the cracks and maintaining the drainage channels.
