Liquefaction Potential of Dams and Foundations. Report 6. Laboratory Strength of Sands under Static and Cyclic Loadings.

Abstract

The strength decrease due to increased pore pressure, previously referred to as liquefaction potential, of four sands, for which laboratory Standard Penetration Tests (SPT) had previously been performed, was evaluated by cyclic triaxial tests at comparable relative densities and confining pressures. Stress-controlled monotonic R tests were performed on one sand to compare potential for strength loss due to increasing pore pressure under static versus cyclic loading. the object of both test series was to develop correlations between SPT-N values and potential for strength loss due to increasing pore pressure. In addition, material constants for evaluating an elastic-plastic constitutive model were obtained during the monotonic R tests. The elastic-plastic constitutive model qualitatively predicts behavior in monotonic R tests.
