This paper describes the effect of improvement against liquefaction by using electrohoresis of Fixative materials in model ground. As a result of being electrohoresis at some Fixative materials, it was found that the case of using solution before mixing Sodium silicate No.3 and Calcium chloride is the most effective of soil improvement. And the effective voltage radient is 1.0V/cm, but the distance between electrodes is 100cm, the strength of improved ground is decreased at the center part. There is a possibility that temperature variation in ground under electric loading has an influence on strength of improved ground.
