Influence of Scale Effect on Strength and Deformation Characteristics of Rockfill Materials. [PDF]
The hybrid method was adopted to model the original gradation of rockfill materials. According to the specification requirements, three simulated gradations of rockfill materials have been obtained. By the same token, the corresponding maximum particle sizes are 20 mm, 40 mm and 60 mm, respectively.

A laboratory-based test procedure for the investigation of slaking-induced changes in geotechnical properties of tailing dam embankment materials [PDF]
Slaking is a process of material parameters alteration resulting from wetting-drying cycles, changes in overburden stress, and chemical interactions. Tailings Storage Facilities (TSF) constructed with materials prone to slaking may experience breaches ...

Experimental Study and DEM Simulation of Size Effects on the Dry Density of Rockfill Material
The initial dry density has a significant effect on the mechanical behavior of rockfill material (RFM). The size effects on the minimum/maximum dry density (referred to as dry density, ρd) of RFM still need further study.

A particle-breakage critical state model for rockfill material
Particle breakage has a significant influence on the stress-strain and strength behavior of rockfill material. A breakage critical state theory (BCST) was proposed to describe the evolution of particle breakage. The breakage critical state line in the breakage critical state theory was correlated with the breakage factor, which was fundamentally ...

Discrete element simulation of crushable rockfill materials
A discrete element method was used to study the evolution of particle crushing in a rockfill sample subjected to triaxial shear. A simple procedure was developed to generate clusters with arbitrary shapes, which resembled real rockfill particles.

Fractures in non-homogeneous rockfill materials from a micromechanics perspective [PDF]
This study investigates particle breakage and cracks propagation of non-homogeneous rockfill materials, particularly conglomerates, from a microscale perspective. The conglomerate's materials were gathered from Masjed-E-Soleyman, MES, rockfill dam, Iran.

Strength and stiffness parameters for hardening soil model of rockfill materials
In recent years, an increasing number of rockfill dams have been constructed in many developing countries around the world. One difficulty in the engineering design and construction of rockfill dams is the characterisation of the rockfill materials ...
