Abstract: At present, there are limited studies on prevention and control measures of slope with granular mixtures. This paper recommends grouting sand to firm sand-sliding slope. Such sand slope has the characteristics of dynamic braking.This paper uses outdoor grouting physical simulation experiment. The grouted sand blocks have the shapes similar to tongue, ganoderma lucidum, cylindrical, long inverted cone and short inverted cone. The effective radiuses respectively are 46.3cm, 26cm, 21.4cm, 16.5cm, 40cm and 29.4cm. The screening tests are done on the stacking structure of granular mixtures influences on the grouting sand consolidation measures. The most main influence is the void ratio. The diffusion radius formula and grouting quantity formula are obtained with computer. The shear tests of consolidate bodies show that the shear strength is enhanced, which indicates the feasibility and rationality of grouting sand consolidation engineering. It is of great reference value for the grouting sand consolidation engineering.
