Comparative studies on design and practice of steep reinforced embankments

The method of steep reinforced embankment using high tensile polymer grids has to be formulated with several assumptions. The present paper deals with instrumented constructions to evaluate them.In two cases of construction, one vertical and the other slanting, several layers of grid are laidin the embankment. As a result of it the tension on the grid is considerably reduced compared with designed tension.These studies reveal that the reinforcing effect is higher than that of the design assumption as the fill material is integrated with polymer grids laidin the embankment. The authors are of the opinion that such an integrated effect should be incorporated in the future designs.
