The Forest Service – U.S. Department of Agriculture and The Federal Highway Administration – U.S. Department of Transportation, “Application guide for launched soil nails: Volume 1” in The Engineering management series (EM7170-12A or FHWA-FPL-93-003). Washington, DC: The Forest Service – U.S. Department of Agriculture, July 1994. This project showed the use of launched soil nails for repair and reinforcement of unstable cut bank and embankment slopes. This was an opportunity for engineers, maintenance personnel, and contractors to explore the potential for launched soil nails. This guide furthers evaluation of launched soil nails as an alternative for road slope repair and maintenance methods. It is best used as a reference for road embankment and fill failures within the limits described in the design methodology section. |

Wu, J. T. H., Lee, K. Z. Z., Helwany, S. B. and Ketchart, K. National Cooperative Highway Research Program (NCHRP) Report 556: Design and construction guidelines for geosynthetic-reinforced soil bridge abutments with a flexible facing. Washington, DC: The Transportation Research Board of the National Academies, 2006. Sponsored by the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA). This report presents the findings of research undertaken to develop a rational design method and construction guidelines for using Geosynthetically Confined Soil (GCS) systems in bridge abutments. It may also be used to design retaining walls, rockfall barriers, and avalanche/debris flow deflection structures. |
