Theoretical considerations and experiments of pullout of soil reinforced by geogrids are reviewed. In order to evaluate the behaviour of soil-geogrid interaction, effective area, which is defined by an effective length of anchor, is emphasized for extensible reinforcements. Three zones: skin friction zone, passive bearing zone and transition friction zone are proposed to estimate pullout resistance since the passive bearing zone is usually not fully developed. The results predicted by a new model presented here are compared with test results and show a good agreement.
