attention of scholars. In this study, by changing the traditional geogrid structure and adding
polymeric anchors to the reinforcement grid, naming it Grid–Anchor (G–A), it is sought to
experimentally analyze the performance of this new system by increasing the Coefficient of
Interaction Ratio in Direct Shear (CIR DS). To achieve this, 16 large-scale direct shear tests
were conducted on a typical geogrid and G–A system. The results of this showed that CIR …
