英文摘要	Scaling off is a common disease of earthen sites with dual structure characteristics in arid areas, and conventional infiltration methods are not ideal for scaling off reinforcement. Using electroosmosis as a reference, an electroosmosis equipment was developed and penetration and reinforcement tests of atmospheric dripping and electroosmosis grouting were carried out. It is found that electroosmosis grouting can uniformly penetrate the radius and expand the penetration depth. On this basis, electroosmosis grouting penetration tests with sodium silicate solution were carried out under different electrode layouts. Regular hexagon was selected as the optimal layout by analyzing the changes in current, grouting volume and energy consumption coefficient during the test. Then, the field reinforcement tests of electroosmosis grouting of three kinds of reinforcement solutions and the related property test of the reinforced soil were carried out with the optimal layout. It is shown that glutinous rice slurry and sodium silicate solution are not suitable for electroosmosis grouting reinforcement, while that, after electroosmosis grouting by SH solution, the bonding between the scaling off layers is tight, and the penetration resistance, hardness, wave speed, wind erosion resistance and disintegration resistance of the soil in the reinforced area are significantly improved compared with the unreinforced soil. © 2021, Science Press.
