Reinforced Soil Structures – BS 8006-1 2010

Steve Corbet

BS 8006- Reinforced and Strengthened Soils has been in use since 1995 however market and design experience has necessitated some revision and enhancement to the original document. This was finalised in late 2010 and was issued to the market. The use of soil reinforced structures, particularly in applications of reinforced basal treatments under embankments or over piles is gaining wide spread acceptance in Australia over recent years. Generally the design of such structures follows no national code with very little local guidance. The talk will cover current overseas design practice in the use of this BS8006 standard for design of soil reinforced walls and slopes with reference to some limited design codes that have been implemented by Road Authorities here in Australia.

An example would be the Queensland Department of Transport Specification TMR 11.06. The talk will also discuss major design differences between alternate European Codes for such structures and BS8006. The talk will focus on the use of geosynthetics as a reinforcing element. General discussion will also talk about conformance testing and acceptance as well as specification techniques to accurately describe product required. Samples of products applicable to the uses discussed will be given out to attendees.
