Abstract  Large soil blocks, produced by grouting the soil are a new reinforcement approach with significant potential. Large-scale direct shear tests were conducted on soil reinforced by blocks simulated with gravel and aluminum cylinders. The results showed that the blocks exhibited significant movement and rotation with interaction chains during the direct shear tests. These increased soil shear strength with significant dilatancy. As the block reinforcement ratio increased, the soil shear strength increased and the soil deformation exhibited increased strain softening and dilatancy from the strain hardening and volumetric contraction. The block shape significantly affected the strength of the reinforced soil.
