Abstract

This paper indicates the possibility of prevention against liquefaction by mixing bentonite in sandy ground with the aid of electrohoresis. If this method is effective, it is useful to improve the subsoil condition of the existing structures by electrically transferring bentonite particles from the outside to the subsoil ground. Experiments were carried out in the laboratory to confirm the effect of soil improvement.<br>The following results were obtained from the experiments.<br>(1) Soil improvement using electrophoresis is effective in preventing sandy ground from being liquefied. (Fig. 3, 5, 6)<br>(2) The effect of improvement increased more by using dispersant or flocculant. (Fig. 9)
