Abstract

Interpretation of drained loading of foundations and anchors requires knowledge of peak and critical state friction angles, as well as the peak dilation angle. Correlations to relative density are typically used to assess these parameters, however, these correlations are not unique, particularly when dealing with low effective stresses that are encountered during model testing or for shallow seabed interactions. Results from a series of cone penetrations tests with inferred relative density profiles are presented to develop a sand specific relative density correlation. The results from laboratory triaxial tests at representative densities and stress levels are compared to cone tip resistance to discuss friction and dilation angle correlations.
