Constitutive Model for Rockfill Materials and Determination of Material Constants
Publication: International Journal of Geomechanics
Volume 6, Issue 4
Abstract
Two types of rockfill materials collected from seven sites are modeled and tested under triaxial loading. A constitutive model based on a disturbed state concept is used to characterize the behavior of modeled rockfill materials. The model is shown to provide satisfactory prediction of the observed behavior of the modeled materials. Characteristics of the particles of the rockfill materials are determined. Relationships are developed between the material constants of the modeled rockfill materials and the characteristics of the particles and these are used to predict the material constants for the prototype size rockfill materials.
