What is BS 8006‑2-Soil nail design about?
BS 8006 is a British Standard that discusses best industry practices for strengthened or reinforced soil.
BS 8006‑2 is the second part of the series that gives recommendations and guidance for stabilizing soil slopes and faces using soil nails. Other methods of stabilization using reinforced soil methods are given in BS 8006‑1:2010 and both parts might be needed for complex structures.
It is a code of practice with information pertinent to UK practice. There is no corresponding European or international standard.
Who is BS 8006‑2- Soil nail design for?
BS 8006‑2 on code of practice for strengthened/reinforced soils is useful for:
- Civil and geotechnical consultants, engineers, designers, contractors
- Site inspectors and assessors
- Operators of national linear infrastructure, e.g., Highways England, Transport Scotland, Welsh Government, Department for Regional Development Northern Ireland, Network Rail
- Technical managers
- Suppliers of reinforced soil structures
- Manufacturers of reinforcement products
Why should you use BS 8006‑2- Soil nail design?
Soil nailing is a construction method that may be used to fix naturally unstable soil slopes or to allow for the safe over-steepening of new or existing soil slopes.
Other methods of stabilization using reinforced soil methods are given in BS 8006-1:2010+A1:2016 and both parts might be needed for complex structures. Additional considerations might be required for unusually loaded or high soil nailed slopes, or where they interface with other structures.
The principal purpose of BS 8006‑2 is to provide design guidance, however, where knowledge of construction methodology is required for design purposes, appropriate paragraphs have been included.
Recommendations on the suitability of different ground conditions for soil nailing are discussed in BS 8006‑2, based on the following principal material types and their characteristic properties:
- Cohesive soils
- Granular soils
- Soft/weak rocks
Overall, BS 8006-2 can assist you in enhancing the efficiency of slopes and faces, as well as improving the mass shear resistance of the slope and the formation of tensile stresses in the soil nails.
What’s changed since the last update?
BS 8006‑2:2011+A1:2017 supersedes BS 8006‑2:2011, which is withdrawn. BS 8006‑2:2011+A1:2017 includes some technical changes with respect to BS 8006‑2:2011. These include:
- Reduction factors made more consistent
- Clarification of potentially ambiguous notation in various parts of the standard
- The advice on atmospheric corrosivity has been updated
- Site investigation to include BS 5930:2015
