Recently, construction of high and steep earth fills using a high water content-cohesive soils is a common practice. Because geocomposites which have sandwiched structure of woven fabric between non-woven fabrics have over the tensile strength of geogrids of woven fabrics and also having the drainage effect of non-woven fabrics. However, current design methods of nonwoven fabric-reinforced earth fills have considered the drainage function only. This paper presents an experimental study on geocomposites-reinforced steep earth fills using Kanto Loam. Comparing both no-reinforced and geocomposites-reinforced earth fills varying, consolidated times, the efficiencies of the geocomposites as drainage and reinforcing material are judged.
