Evaluation of Shear Strength and Dilatancy Behavior of Reinforced Soil from Direct Shear Tests

Source

In order to evaluate the shear strength and dilatancy behavior of coarse granular soils reinforced with geogrid a large direct shear apparatus (1000×1000×940 mm) was built. A series of shear tests were carried out to study the effect of geogrid orientation and soil volume changes on shear strength. A numerical model is proposed to calculate the shear strength increase. This is verified by the experimental results. Tensile strains in the geogrid can also be calculated using this model.
