Abstract
From the studies on retaining walls made of sand reinforced by continuous fibers, the stability of the overall structure seemed to be affected by the deformation of the reinforced sand itself. To reduce the deformation of the wall, the use of geogrid together with the fiber-reinforced sand wall was suggested. Pull-out tests on geogrid in sand reinforced by continuous fibers were carried out as the first step of the study. It was found that both the cohesion component and the frictional resistance of the geogrid in the reinforced sand were higher than those in non-reinforced sand. Therefore, the reinforcement by the continuous fibers seems to be effective for the pull-out resistance of geogrid in sand.
