| Abstract | The stress strain behavior and strength characteristics below the state boundary surface is investigated by conducting ten CIU tests (with OCR values of 1, 1.4, 1.6, 1.8, 2, 3, 4, 6 and 8) as well as constant mean normal stress (constant p) drained tests (with OCR values of 1, 1.2, 1.4, 1.6, 1.8, 2, 3, and 4). A novel feature of the testing programme is that all samples had nearly the same pre-shear voids ratio, and, stress reversals were carried out at various levels of deviator stress to separate the recoverable strains from the non-recoverable strains. Pseudo-moduli were evaluated for loading, unloading and reloading stress paths and the results are presented with respect to the deviator stress as well as the shear strain. Pore pressure parameter, A is also evaluated and presented with respect to the shear strain. The recoverable and non-recoverable shear strains are computed both for the undrained and constants p drained conditions. These strains are then presented in the form of contours in the (q,p) plot. Also the undrained strength and the constant p drained strength are presented as ratios of the effective axial stress (after pre-shear consolidation) for various OCR values. |
