“…Jiang et al [8] studied the mechanical properties of the reinforced coarse-grained soil with hexagonal reinforcement network through the large-scale triaxial test and found that the strength and stiffness of the coarse-grained soil can be significantly improved after reinforcement. Abdelkader et al [9] explored the influence of geotextile on the stress-strain and volume variation characteristics of reinforced sand through the triaxial test and found that the geotextile could increase the shear strength and reduce the expansion of the specimens. Carlos et al [10] used filament nonwoven fabric as reinforcing material and studied the effect of reinforcement on fine-grain soils using triaxial tests.…”

To study the effect of three-dimensional reinforcement arrangement on the behavior of a gravelly sand, triaxial tests were performed on specimens reinforced with geogrid sheet, geogrid cell, and one and two layers of geogrid sheet and geocell combination. Specimens with a diameter of 100 mm and a height of 200 mm are sheared under drained condition to monitor the variation of axial and volumetric strains with axial loading under different confining pressures. The results showed that the reinforcement schemes have different effects on soil strength improvement. The inclusion of double layers of geogrid sheet and geocell reinforcement could increase both the apparent cohesion and friction of the reinforced soil. The stress-strain relationship could be modelled with a modified hyperbolic model, which can capture the softening strain behavior of the specimens after peak strength.
