Stability of Slopes for Closure of Old Waste Dumps
Old waste dumps often have steep slopes because waste has been tipped over from the top of the dump. For the closure of such dumps, low permeability cover systems are to be provided to control leachate formation as well as to capture landfill gas. The stability of such cover systems is governed by the shearing resistance that develops at the interfaces of various components of the cover systems. This paper describes a case study for closure of an 18 m high municipal solid waste dump. It highlights the influence of slope angle, slope height, surface roughness of geomembrane and tensile strength of veneer reinforcement on the stability of slopes. The impact of seepage force and the earthquake loading on the stability is also discussed. The case study shows that use of textured geomembrane, berms at small heights and veneer reinforcement of high strength, all help in the improvement of slope stability.
