Effects of Maximum Particle Size on the Shear Behavior of Coarse-Grained Soil: Direct Shear Tests and Discrete Element Simulations

To investigate scale effects on the shear strength and mesoscale load-bearing structure of coarse-grained soil, four specimen groups with maximum particle sizes of 10, 20, 40, and 60 mm were tested in large-scale direct-shear tests under normal stresses of 100–400 kPa. Corresponding three-dimensional PFC3D discrete ele...
