A Study of the Rockfill Material Behavior in Large-Scale Tests [PDF]
Civil Engineering Infrastructures Journal, 2013 Inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. Since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to ...

Testing and modeling of rockfill materials: A review
Journal of Rock Mechanics and Geotechnical Engineering, 2016 AbstractThe research development of rockfill materials (RFM) was investigated by a series of large-scale triaxial tests. It is observed that confining pressure and particle breakage play important roles in the mechanical property, dilatancy relation and constitutive model of RFM.
