Fractures in non-homogeneous rockfill materials from a micromechanics perspective [PDF]
Journal of Hydraulic Structures, 2022 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
Soils and Foundations, 2021 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 ...

Discrete element simulation of crushable rockfill materials
Water Science and Engineering, 2013 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.

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 ...

A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams
International Journal of Distributed Sensor Networks, 2018 Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the ...
