The objective of this study was to investigate the time-dependent behavior of tropical soils from Hawaii by conducting carefully controlled long-term creep tests under drained conditions. Time dependency issues investigated include creep behavior under sustained anisotropic stresses, rate effects during deviatoric loading, was well as strength changes associated with secondary consolidation and aging. Correlations were sought between creep deformation and Atterberg limits to provide empirical correlations that can be referred to when time consuming and expensive tests of the type conducted herein are not feasible. In addition, the testing program was aimed at determining specific material constants for constitutive model development and verification.
