    Abstract

    Laboratory rod shear tests were conducted on offshore clay samples with a test device adapted from a conventional triaxial cell. The load rod surface had an unpolished finish. Tests were of the fast type with controlled rate of displacement. The program included tests on normally consolidated specimens and measurement of response up to or approaching residual conditions. Failure conditions are assessed by comparing the test data with soil failure from an effective stress framework and rod-soil rupture. For these Gulf of Mexico clays, the experimental data compare well with a stress history dependent ratio of shear stress to consolidation stress. Rod shear results can be influenced by local drainage, leading to increases in strength of clays.
