Abstract

One of the techniques of stabilization soil is the electrical method. In this method, stabilization of fine-grained soils, especially saturated clay soils, is done by reducing the thickness of the double water layer by establishing an electric current. In this study, to improve and stabilize soft clay soils, the electrokinetic injection method, which The index results of the studies showed that the use of this method increases the unconfined compressive strength from 98 kPa to 223 kPa, decreases the water content from 24  to 15/2 and the plasticity index from 24 to 10 and Soil porosity decreases from 0/675 to 0/443. The results of the chemical analysis confirm the correctness of the physical results in the scanning electron microscope images. According to the water content, Etterberg limits, unconfined compressive strength, and consolidation tests, it was determined that the best performance is related to the use of plate aluminum electrodes with a voltage of  1/5.
