Abstract In this study, a series of numerical pullout tests was performed using the discrete-element method (DEM) to investigate the micromechanical behavior of geogrid pullout and the effect of geogrid tensile stiffness. Geogrid–soil interaction during pullout was investigated not only through displacement fields and force chains inside the soil but also via the quantitative displacement and force distributions along the geogrid. The active and inactive zones were defined based on the displacement fields in the soil, and the displacement corresponding to the boundary between the active and inactive zones was found to be 1.25 mm in this study. |
