The influence of slag powder, cement and bentonite on the permeability coefficient of granite residual soil at different incorporation ratios was analyzed by means of seepage test with variable head. Meanwhile, the permeability coefficient was compared with that of the original granite residual soil. It is found that the effect of slag powder on reducing the permeability coefficient of granite residual soil under non-alkaline environment is limited. The effect of cement on decreasing permeability coefficient of granite residual soil is obvious. Bentonite has the best effect on reducing permeability coefficient of granite residual soil.
