Abstract
Recently developed geocomposite has sandwiched structure of woven fabric between both non-woven fabrics and has over the tensile strength of geogrids of woven fabrics and also having the drainage effect of non-woven fabrics. However, current design methods of non-woven fabric-reinforced earth fills have considered the drainage function only. Therefore, this paper proposes a new design method of earth fill structures considering the reinforcing effect together with strength increase of the volcanic loam caused mainly by drainage. This paper considers also the soil-fabric interaction and the effect of geocomposite on the final performance of steep earth fill structures.
