This paper examines pull-out test results of geogrid specimens embedded in a granular soil. The influence of specimen geometry, soil height and sleeve length on the pull-out force of the geogrid specimen is discussed and the results of nine pull-out tests are analysed. Soil and geogrid properties are also fully described and the soil-geogrid interaction behaviour is studied. The conclusions of this study are as follows: the pull-out tests are reproducible; the influence of the geogrid specimen length on the geogrid specimen pull-out response is a function of the density of the granular soil; the influence of the geogrid specimen width on the pull-out response of the geogrid specimens tested is minimal; the effect of the soil height above and below the geogrid specimen on the soil-geogrid interface shear resistance is minimal for the two soil heights tested; and, the placement of a 0.20 m long steel sleeve in the front wall of the pull-out box reduces the magnitude of back calculated soil-geogrid interface shear resistance because it minimizes the effects of friction that are caused by the roughness of the front wall.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
