State-Dependent Constitutive Model for Rockfill Materials
International Journal of Geomechanics, 2015AbstractA series of large-scale triaxial compression tests on Tacheng rockfill material (TRM) showed that the dilatancy and stress-strain behaviors were significantly influenced by density and pressure. The critical state friction angle of TRM decreased with an increase in the initial confining pressure.

Unmanned rolling compaction system for rockfill materials
Automation in Construction, 2019Abstract The compaction quality of earth–rock dams is mainly controlled by compaction parameters (the number of compaction passes, compaction trajectory, vibration frequency, lift thickness, and driving speed) during construction. However, relying on the operator to implement control of the compaction parameters can result in unrolled, cross-rolling,

Large Scale Testing of Rockfill Materials
Journal of the Soil Mechanics and Foundations Division, 1967A brief description is made of the rockfill laboratory of the Comision Federal de Electricidad in Mexico. Equipment is available for large-scale (specimens 113 cm in diam) triaxial and compressibility testing of granular materials with maximum particle size up to 20 cm, under lateral pressures up to 25 kg per sq cm.

Tests on Cohesionless Materials for Rockfill Dams
Journal of the Soil Mechanics and Foundations Division, 1969An account is given of the tests carried out at the ISMES laboratories to set up techniques for testing cohesionless rockfill dam materials. A newly devised chamber formed of alternating rigid and deformable rings for confined compression tests is described.

Influence of Different Stress Conditions on Behavior of Rockfill Materials
Geotechnical and Geological Engineering, 2011Rockfill material is the most readily available and the most flexible material for the construction of dams especially in the seismic prone regions. The material is obtained either by blasting available rock or is collected from the alluvial deposits of the river.

Automatic learning for patterning the behavior of rockfill materials
2015In order to deal with the ill-posed problem of material parameter identification for rockfill materials, a procedure based on machine learning is proposed. In this investigation the results of a comprehensive set of tests on rockfill materials are examined.

Experimental evaluation of collpase deformation behavior of a rockfill material
2015To investigate the saturation induced collapse deformation behavior of rockfill material, a set of large-scale triaxial tests were conducted in saturated and dry-saturated conditions. Specimens were tested under various confining pressures. For drysaturated tests, specimens were sheared in various stress levels.
