The paper describes a slope failure involving an unreinforced geosynthetic clay liner (GCL) in a municipal solid waste (MSW) landfill liner system. The precise mechanism for the shear movement of the interim slope is not known. However, the significant damage ...

Dry and hydrated specimens of an unreinforced geomembrane - backed geosynthetic clay liner were sheared against a textured geomembrane using a torsional ring shear apparatus to study the shear behavior of geomembrane encapsulated bentonite.
