<p>A method of stabilising slopes of a soil embankment is provided using a stabilisation system for slopes having generally less than 45 degrees of inclination from horizontal. The system comprises a plurality of soil nails which are penetrated into the siopes to provide internal soil stability and a biotechnical facing on a surface of the slope to inhibit surface erosion and shallow failure of the slope. A geosynthetic layer comprising a mat, mesh or fibrous material is laid across the slope adjacent the surface to assist in establishing vegetation thereon. A retaining wall structure is preferably mounted on the crest of the slope to extend transversely to the slope. The retaining wall structure at the crest provides a stable base for supporting the embankment shoulder.</p> |
