Abstract The electroosmotic grouting method has become an ideal reinforcement method for the scaling off earthen sites due to its advantages in uniform penetration radius and extended penetration depth. However，due to the fact that this method is still in the experimental stage，there are important problems such as low electro-osmosis efficiency and unclear effective permeability range，which restrict its high-quality promotion and application. The best electroosmotic grouting method was selected through the electroosmotic grouting reinforcement experiments of five kinds of power supply-liquid supply methods，and then the field reinforcement experiments with different on-off liquid time ratios were carried out by the preferred power supply-liquid supply method. Based on the experimental results，a two-dimensional model of effective permeability range was established by multiple linear regression. On the basis of establishing the control equation of scaling off of electroosmotic grouting reinforcement，the numerical simulation results，field experimental values and model calculation values were compared. The results show that the ideal electroosmotic grouting method is continuous power supply-intermittent liquid supply，and the best on-off ratio is 6∶1，the effective permeability range is affected by the total permeability amount of the solution，the porosity of the soil，the on-off ratio and the electrode spacing. The effective permeability range is equivalent to the electrode spacing within 0–1 cm，while the effective permeability range within 1–10 cm obeys the linear law of different slopes with 4 cm as the segmentation point.

Key words： soil mechanics electroosmotic grouting scaling off electroosmotic efficiency solid content permeability range
