DEFORMATION-BASED MODEL FOR REINFORCED SAND

This paper presents a closed-form solution for the length of a reinforcement in tension versus shear displacement, and its use in a rigid-plastic model for the work to deform reinforced soil in direct shear. The analytical results and experimental data are described. It was found that in direct shear tests, under conditions where a shear zone can form, the length of a reinforcement in tension is many times greater than the magnitude of the shear displacement. This length increases with decreasing reinforcement concentration and soil-reinforcement bond strength, and increases with increasing reinforcement. These and other conclusions drawn from the study are discussed.
