Electrokinetic stabilization is a newly developed technique, which was pioneered by Cassagrand in1940 and has been employed in railway embankment stabilization. Compared with conventionalfoundation treatment methods, electrokinetic stabilization performs more effectively with shorter timeson soft clay foundations with a high content of fine grains and a low hydraulic coefficient. However,electroosmosis (EO) has not been widely used in practical engineering, especially in large-scaleapplications, due to a lack of understanding of the mechanism of EO treatment and the errors betweenthe theoretical predictions and experimental results, which cannot be ignored. The purpose of thispaper is to briefly review the history of electrokinetic stabilization on soft soils, includinginvestigations into the mechanism, laboratory and field tests of the critical influencing factors, and thedevelopment of theoretical and numerical models and methods to improve the efficiency of EOtreatment. In addition, directions for future research are discussed.
