Abstract
Most of the design methods for the geogrid reinforced-soil wall are based on the theory of rigid-plasticity which takes no account of displacement and deformation of reinforcing material in soil. However, pull-out resistance of the geogrid in soil depends on the displacement of the grid junction.
In this paper, finite element analyses of the geogrid reinforced-soil walls are performed. The method used here is capable of taking account of the mechanism of pull-out resistance of the geogrid in soil obtained from the pull-out tests on the geogrids. A practical design method for the geogrid reinforced-soil wall is proposed, which consists of a set of design charts determined from the finite element analyses.
