The San Andreas fault in California has long been thought to be far weaker than given by the Anderson-Byerlee state because of the lack of a heat-flow anomaly adjacent to the fault as predicted by a steady-state conductive model of frictional heating. Here ...

Torsional ring shear tests were performed to evaluate the effect of shear displacement rate on the internal shear strength of a needle-punched geosynthetic clay liner (GCL) under different normal stresses. The test results suggest that the internal shear strength ...

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.
