Abstract Anchored geosynthetics are able to withstand higher tension and provide higher anchorage capacity. The simple run-out and wrap-around anchorages are two commonly used configurations in anchored geosynthetics. However, the influence of geometric parameters of different anchorage configurations on pull-out performance is still problematic. To study the influence of anchorage angles on pull-out resistance of the geotextile wrap around anchorage, two geometric control variables, namely, the top and bottom anchorage angles, were introduced and investigated experimentally and theoretically. A series of pull-out tests were carried out on the geotextile anchorages with varying configurations embedded in sand, including the simple run-out and wrap around anchorages that were configured at varying top and bottom anchorage angles. Three stages were summarised to interpret the mobilisation of pull-out resistance of the geotextile wrap around anchorage during the pulling process. It was found that the smaller the bottom angle, the higher the initial pull-out resistance achieved at early and middle stages, while the larger the top angle, the higher the final pull-out resistance achieved at final stage. In addition, theoretical studies on pull-out resistance of the geotextile wrap around anchorage with varying anchorage angles were also carried out based on the static equilibrium analysis.
