The behavior of root-soil system has raised more and attention in both ecological geotechnical fields. In this study, a two-dimensional discrete element method is employed using PFC2D to simulate the root-reinforced soil. root mimicked by chains bonded discs, while soil modeled granular particles. tensile strength interdiscs’ bonding strength. Three laboratory tests were studied calibrate micromechanical parameters DEM. Finally, direct shear on rooted are simulated investigate influence...
Global stability analysis is a key component of mechanically stabilized earth (MSE) wall design, especially those constructed over marginal soils. When limit equilibrium used for MSE incorrect factors safety can be predicted depending on the shape assumed failure surface. The use ground improvement, such as aggregate piers (AP), further complicates analysis. A mobilized bearing capacity (MBC) approach presented which highlights direct relationship between global and capacity. Results from...
Graded crushed stone (GCS), as a cheap and essential component, is of great importance in road construction. The irregularity variability particle shape known to affect the packing characteristics GCS, such compactness void ratio. In this study, realistic outline first automatically extracted based on digital image processing deep learning algorithms. Then, elongation ( EI ), roundness Rd roughness Rg ) GCS are quantified by evaluation Moreover, establishment library, gravity deposition with...
Rockfill materials, conducted by impermeable stone, are frequently used in subgrade construction projects. The irregularity and variability of particle shape demonstrated to affect the mechanical properties rockfill subgrade, such as void ratio coordination number. This study first identifies contour machine learning algorithms, including AdaBoost, Cascade, sliding windows. Then, evaluation indexes length flatness, edge angle, roughness quantified, statistical analysis each index is...
