BS 8006-1:2010+A1:2016

This British Standard contains recommendations and guidance for the application of reinforcement techniques to soils, as fill or in situ, and to other fills. The standard is written in a limit state format and guidelines are provided in terms of partial material factors and load factors for various applications and design lives.

This code is to be read in conjunction with BSEN1997‑1:2004, NA to BSEN1997‑1:2004 and BSEN14475:2006.

BSEN1997‑1:2004 does not cover the design and execution of reinforced soil structures. The values of partial factors and load factors given in BSEN1997‑1:2004 have not been calibrated for reinforced soil structures. BSEN1997‑1:2004 is not for use in the design and execution of reinforced soil. The partial factors set out in BS8006‑1 cannot be replaced by similar factors in BSEN1997‑1:2004.

The code is divided into eight sections. Section1 identifies the scope, definitions and notation of the code. Section2 describes the concepts and fundamental principles of reinforced soil. Section3 provides recommendations for the use of materials where existing standards are available. Where materials are used that are not covered by existing standards or where known materials are to be used in ways not covered by existing standards Section4 gives recommendations for the testing and approval of such materials.

Sections5 to 8 relate to design, construction and maintenance of walls and abutments, slopes and foundations. They include specific recommendations for characterization of the soils to be used and other factors affecting the design and performance of the structures. Emphasis is placed on quality control both with regard to the consistency of the properties of the fill and reinforcing materials and to the handling of the materials on site.

In line with current practice the design methods described are based on limit state principles. The partial factors included are based on previous experience and have been calibrated to maintain consistency with current practice.

The clauses are supplemented by a substantial list of references to enable the user to consider in greater depth the applications of the technique.
