Abstract
Reinforcing effect of geogrid-reinforced soil structures is evaluated by the tensile force of geogrid. However, our research has made clear the existence of the additional confining effect which is independent of tensile force of geogrid.
The factors influencing the confining effect are the shape of geogrid, the density of soil and so on. In this paper, we experimentally examine the effect of the shape of geogrid. In order to evaluate the shape characteristics quantitatively, the shape index, R, has been proposed. The relation between Shape Index, R, and the confining effect was shown.
