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.
BS 8006‑2 on code of practice for strengthened/reinforced soils is useful for:
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:
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.
BS 8006‑2:2011+A1:2017 supersedes BS 8006‑2:2011, which is withdrawn.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:
