...T.D. Stark; E.J. Newman ABSTRACT: This paper describes a final cover slope failure at a municipal solid waste containment facility. The lessons learned from this case history include: (i) slope stability analyses should be conducted whenever field conditions differ from initial design assumptions...

... obtained in limit equilibrium stability analyses were close to the observed field failure surfaces. These analyses used measured reinforcement forces and resulted in Bjerrum correction factors around μ = 0.60 for the two embankments. These analyses considered the measured reinforcement forces and three...

Stability and deformation analyses were conducted, along with a comparison between conventional GWR structures and modified systems. The influence of the foundation and scouring was also...

... are discussed. It is concluded that the partial consolidation provided by PVDs and the tension mobilized in reinforcement can substantially increase embankment stability. However, creep of geosynthetics can decrease the embankment failure height. The mobilization of reinforcement during and after embankment...
