“…The three-sigma rule has been used by Sabatini et al (2002) to quantify the variability of geosynthetic/soil interface strength. In this paper, variability of interface strengths has been expressed as a function of the mean using coefficient of variation (V) defined as: (Koerner and Koerner 2001).…”

“…PROBABILITY OF FAILURE STABILITY ANALYSIS 4.1. Analysis method for probability of failure Risk assessment of landfill stability using probability of failure (P f ) has been discussed by Koerner and Koerner (2001), Sabatini et al (2002) and McCartney et al (2004). All employed the first-order, second moment reliability-based methodology (Duncan 2000).…”

“…There have been a number of failures, as discussed in the introduction, with sliding taking place along one or more interfaces within the lining system. Slope and waste geometries similar to those used by Sabatini et al (2002) were selected for the reasons discussed above. Figure 17 shows the problem analysed with the key variables defined.…”

“…This makes selection of appropriate shear strength values for use in design problematic. The relatively high rate of landfill failures has led some researchers to propose that risk assessment using probability of failure analysis can be used to quantify uncertainty in selection of appropriate interface shear strengths (Koerner and Koerner 2001;Sabatini et al 2002;McCartney et al 2004). …”

“…The use of reliability assessment in landfill stability is demonstrated through consideration of two common landfill design cases: veneer stability and waste slope stability. Veneer stability has previously been used by Koerner and Koerner (2001) and McCartney et al (2004), and waste slope stability by Sabatini et al (2002), to demonstrate the sensitivity of landfill design to interface variability. These two design cases were selected for use in this study in order to add to the existing published information on relationships between probability of failure and traditional factors of safety.…”

Failure of modern landfills by slippage of lining materials and waste bodies is not uncommon. The majority of failures are controlled by slippage at interfaces between lining components. Information on variability of interface shear strength is required both to carry out limit equilibrium stability analysis using characteristic shear strengths and to analyse the probability of failure. Current practice is to carry out a limited number of site-specific tests, and this provides insufficient information on the variability of interface strength for design. A summary of measured strengths and an assessment of variability are presented for seven generic interfaces common in landfill lining systems. This combines values from the international literature, from an internal database, and from the results of repeatability testing programmes. The implications of variable shear strength are examined though failure probability analysis for two common design cases – veneer and waste body slippage – and this adds to the small number of studies published previously. The reliability analyses show that relatively high probabilities of failure are obtained when using variability values from the literature and an internal database, even when factors of safety ≥ 1.5. The use of repeatability data produces lower probabilities for typically used factors of safety, although they are still higher than recommended target probability of failure values.

Geosynthetics form an integral part of engineered municipal solid waste (MSW) landfill lining systems, as they provide cost saving and technical benefits. Their introduction in lining systems, however, has presented new potential interfaces for shear failure especially on bases and on side slopes of engineered MSW landfills. In the laboratory, interface shear strength parameters used in slope designs of landfill lining systems are determined through single-interface testing configurations as per ASTM D5321-20 and D6243-20 standards. However, single-interface testing configurations do not provide a clear understanding of shear strength transfers among the lining components and does not aid in pin-pointing the interface facilitating failure especially when a multi-layered lining system has been proposed. Multi-interface testing configurations present an alternative that may address such limitations. But there is minimum information available on this type of testing as it is not stipulated in any official laboratory testing standard. This study was conducted to provide an understanding of the potential use of multi-interface testing configurations of MSW landfill liners, through identifying similarities and dissimilarities to the single-interface testing configurations. These interface tests were conducted on geosynthetics and geomaterials from a proposed lining system of a new landfill cell in South Africa.
