Abstract
With increasing use of geosynthetic applications in earth structures the need to develop more efficient reinforcement elements becomes evident. In this paper a conventional and an innovative geogrid system (named Grid-Anchor) are tested. The Grid-Anchor system consists of a conventional geogrid with anchors attached to it. The pull-out test has been used to highlight the capabilities of the product. Experimental investigation along with numerical studies using a finite element computer code was carried out. It was found that the ultimate pull-out resistance of a Grid-Anchor is more than that for an ordinary geogrid. Analytical study has been performed and the effect of an anchor group on the ultimate resistance of a geogrid was investigated.
