Influence of Scale Effect on Strength and Deformation Characteristics of Rockfill Materials. [PDF]
Materials (Basel), 2022 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.

Unified modeling behavior of rockfill materials along different loading stress paths
Soils and Foundations, 2022 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.

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 ...
