Drained residual shear strength is applicable to slopes containing preexisting shear surfaces and preexisting landslides. Laboratory ring shear testing by various researchers suggest the possibility of strength gain along preexisting shear surfaces which had ...

Drained residual shear strength is considered applicable for the analysis of slopes with a preexisting shear surface. Torsional ring and direct shear tests were performed to investigate the gain in strength, if any, along a preexisting shear surface with time. ...

This paper presents recommendations for selecting the type and magnitude of drained shear strength parameters for analysis of landslides. In particular, the importance, existence, and use of the cohesion shear strength parameter is reviewed. For slope stability ...

<p>Soil slope instability concerning highway infrastructure is an ongoing problem in Iowa, as slope failures endanger public safety and continue to result in costly repair work. Characterization of slope failures is complicated, because the factors affecting ...

<p>Investigation of residual shear strength with the Bromhead ring shear apparatus and evaluation of factor of safety with different types of limit equilibrium methods for the Hyogo Prefecture Japan.</p>

Reevaluation of the fourth avenue landslide in Anchorage that occurred during 1964 Alaskan earthquake based on ring shear and in situ vane shear tests of the undrained peak and residual shear strength of bootlegger cove clay. Comperison with back analysis ...

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 ...

A torsional ring shear apparatus and test procedure are described for measuring soil - geosynthetic and geosynthetic - geosynthetic interface strengths based also on back analysis of Kettleman Hills Waste Repository in California.
