摘要：
One-way shearing test of the coarse-grained soils and the reinforced earth was carried out under different normal stresses. The one-way shearing curves of coarse-grained soils and reinforced earth are similar. The changed curves of normal direction deformation with the shearing distance of coarse-grained soils and reinforced earth are also similar. Trend, of the curve for the normal direction deformation and the reinforced earth is shrink at first and then expand continually. Under different vertical stresses, the difference of the curve for the normal direction shift and the reinforced shift is larger. Compared with raw coarse-grained soils, the cohesive force(c) of the reinforced earth increased, but the angle internal friction (phi) decreased for the reason that the articulation effect between the grilling, and the coarse-grained soils was reduced in the progress of shearing. So, the anti-shearing strength was decreased.
