Abstract

A series of true triaxial numerical tests were carried out on reinforced granular soils based on DEM method, effects of reinforcement layers and intermediate principal stress ratio on the strength characteristic of granular soils were conducted. The simulation results show that the shear strength of reinforced soils can be improved with the increase of reinforcement layers. However, the improvement effect becomes weak with increase of the intermediate principal stress ratio. Furthermore, the shear strength of granular soils will decrease with the increase of intermediate principal stress ratio b under constant P stress path, the maximum shear strength can be obtained in case of b=0 test, while the minimum shear strength appears under b=1.0 condition.
