Influence of Soil Strength on Reinforced Slope Stability and Failure Modes

Finite element method was applied to analyze the reinforced slope stability in the paper, and under conditions of reinforcement materials matched with soil of various strengths, the shear zone characteristics and failure modes, as well as the influences of the soil strength parameters on reinforced effect, were also investigated. Results showed that reinforcement had increased significantly the apparent cohesion of soil, the reinforced sandy slope was damaged along a certain sliding arc, and appeared the cohesive slope destruction characteristics, the failure modes of the traditional sand slopes were varied correspondingly, and the integrity and stability of sandy slopes were all improved. Even with the same reinforcement material, reinforcement effect on the stability of the slope differed with various index of soil strength. The selection of the strength combinations of reinforcement and soil within a certain range could sufficiently mobilize the interactions to improve the reinforcement effect. Results also showed that reinforcement could improve the soil strength and enhance the stability of the slope to a certain extent, but could not change the main body of soil in the reinforced slope. Considering the combination of reinforcement and soil is crucial to ensure the reinforced effect in reinforced slope design.
