Proposals on the Design Method for Geogrid Reinforced Steep Embankments

Abstract

The design method for steep embankments reinforced with geogrids is usually adopted in Japan on the basis of Jewell's two-part wedge analysis. However the assumptions that are made in Jewell's method differ from the Japanese embankments or retaining walls design criteria and hence the adopted design method gives results on the safety-side, which was found out from field measurements of test or practical construction. In this report the revised design method is proposed with a view to obtain an optimum design method for the steep reinforced embankments.
