Open publisher page 11 citations

Abstract

The effect of stress rotation on clay strength can be significant. This study reviews previous laboratory strength data from 100 natural and artificial clay soils which were sheared to failure in both compression and extension using one or more of the following procedures: isotropic triaxial, anisotropic triaxial, plane strain, cubical triaxial, or hollow cylinder. Compression and extension tests are examined in terms of both the undrained strength and effective friction angle. Overconsolidation strength data are also reviewed. Such correlations are useful in evaluating laboratory test results and as data sources for preliminary design analysis. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
