Characterization of the Rate-Dependent Behavior of a High-Plasticity Stiff Sedimentary Clay

CODEN: GTJODJ

Abstract

This study investigates the influence of structure and stress history on the strain-rate-dependent (viscous) stress–strain behavior of a very-high-plasticity stiff sedimentary clay. Oedometer, ring shear, and triaxial compression tests with step changes in strain rate have been conducted on specimens of Søvind Marl with the aim to characterize and quantify the rate-dependent behavior of the clay in both compression and shearing pre-peak, post-peak, and at residual state. Moreover, from a comparison of intact specimens and normally consolidated and overconsolidated reconstituted specimens, the influence of diagenesis and mechanical overconsolidation on the rate-dependent behavior is assessed and discussed in the light of findings from similar studies on other high-plasticity clays.
