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 ...

Current design guidelines for geosynthetic-reinforced soil structures disagree over the shear strength parameters that should be selected to characterize the backfill material. Most geosynthetic reinforcing materials are classified as extensible inclusions ...

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 ...

The drained residual shear strength of overconsolidated clays is an important parameter in assessing the stability of slopes that contain a preexisting shear surface. Laboratory Bromhead ring shear apparatus and 32 clay evaluation of drained residual shear ...

There are correlations between the residual strength and the soil index properties. The soil index are as follows; the clay fraction Fclay as related to physical property of soil particle, the pH and the salinity of related to chemical property of pore water ...
