Landfill stability and integrity: the UK design approach

This paper highlights the design considerations, in terms of stability and integrity, for EC Landfill Directive compliant sites. The paper details a design chart based on research and development reports produced for the Environment Agency (England and Wales) intended to guide designers and highlight areas for consideration in each of six aspects of landfill construction: subgrade, basal lining system, shallow-slope lining system, steep-slope lining system, waste slopes and capping lining systems. The paper is not intended to offer design methodologies in terms of which calculation methods should be adopted, but to provide designers with a framework in which to apply engineering skill and judgement and to highlight challenges.
