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 ...

Study of several field case histories has shown that the difference between two - and three - dimensional factors of safety is most pronounced in cases that involve a translational failure. Two and three dimensional slope stability analysis of field case histories ...

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.

Results of torsional ring shear, direct shear, and triaxial compression tests on cohesive soils reveal that the fully softened shear strength is stress - dependent and related to the type of clay mineral and quantity of clay - size particles. An empirical ...

<p>This paper describes torsional ring shear tests on interfaces comprised of high density polyethylene (HDPE) geomembranes nonwoven geotextiles and a drainage geocomposite. Four textured geomembranes with three different manufacturing techniques are utilized ...

Results of torsional ring shear tests on cohesive soils reveal that the drained residual strength is related to the type of clay mineral and quantity of clay-size particles. The liquid limit is used as an indicator of clay mineralogy, and the clay-size fraction ...

The main factor affecting the drained residual strength measured in the Bromhead ring shear apparatus is the magnitude of wall friction developed along the inner and the outer circumferences of the confined specimen. A new specimen container is proposed for ...
