    Abstract

    The particular sequence of axial load and confining-stress change employed in a multistage triaxial test can dramatically influence the stress paths imposed on triaxial specimens, as can isotropic and anisotropic consolidation. The cumulative radial strain in isotropically consolidated specimens can be as much as three times greater than that in anisotropically consolidated specimens at the end of the third stage of a test. Cumulative axial strain was about equal in isotropically and anisotropically consolidated specimens, even though the isotropically consolidated specimens apparently experienced less total compressive strain by the end of a test. While increased strain did not appear to influence the results from multistage triaxial tests on relatively insensitive residual soils, the influence on tests results for more sensitive soils may be significant.
