Practical nonlinear constitutive model for rockfill materials with application to rockfill dam

Computers and Geotechnics, 2020
Abstract In this paper, a nonlinear constitutive model for rockfill materials is proposed to account for the coupling influence of the mean effective stress p and the deviatoric stress q on the deformation of rockfill materials. In the model, the stress-dilatancy relationship derived from the microstructural changes of granular materials is adopted ...

Evaluation of Properties of Rockfill Materials

Journal of the Soil Mechanics and Foundations Division, 1972
A modeling technique has been used to determine the properties of rockfill materials. The results indicate that the mechanical properties of the field rockfill materials can be predicted with a high degree of accuracy by a series of tests with modeled rockfill materials in the laboratory. Modeling of the rockfill materials did not materially affect the
