BS 8006: 1995 Code of practice for Strengthened/reinforced soils and other fills
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This British Standard contains guidelines and
recommendations 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 of safety
margins in terms of partial material factors and
load factors for various applications and design
lives.
The code is divided into nine sections.
Section 1 identifies the scope, definitions and
notation of the code. Section 2 describes the
concepts and fundamental principles of reinforced
soil. Section 3 provides recommendations for the
use of materials where existing standards are
available. Where materials are used which are not
covered by existing standards or where known
materials are to be used in ways not covered by
existing standards section 4 gives recommendations
for the testing and approval of such materials.
Sections 5 to 9 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.
Much of the existing practice of reinforced soil is
based on the use of limit equilibrium design
methods which incorporate a global factor of
safety. In keeping with the principles of limit state
design, consistent structural dimensions and
materials quantities have been maintained with
existing practice by calibration of the partial factors
in the limit state design relationships in this code.
This approach is different to that adopted by some
concurrent codes of practice, e.g. BS 8002: 1994,
which rely on the use of 'worst credible'
safety.
