Discrete element simulation of crushable rockfill materials [PDF]
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.

Effects of toe configuration on throughflow properties of rockfill dams [PDF]
Rockfill dams must be equipped with defence mechanisms to counteract the destabilizing effects of throughflow forces under accidental leakage scenarios. A key component of the rockfill dam overtopping system is the rockfill dam toe, constructed in tandem

Hydraulic and structural evaluation of rockfill dam behavior when exposed to throughflow and overtopping scenarios [PDF]
Dams are vulnerable to extreme flood events in turn leading to accidental overtopping. This inparticular applies to rockfill dams comprised of pervious and erodible material.

Particle breakage characteristics of rockfills under complex stress paths
A series of conventional triaxial tests, isotropic compression tests and complex stress path triaxial tests are conducted to investigate the particle breakage characteristics of rockfills, which are evaluated quantitatively by using the relative breakage

Unified modeling behavior of rockfill materials along different loading stress paths
Rockfill materials used for dam construction show obvious stress path dependency during construction process. The constitutive model for rockfill materials are mainly established based on conventional triaxial test.
