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 ...

Extrapolation-Based Scale Effect Model for Granular Heap Modulus
Advances in Civil Engineering, 2023 The numerical analysis was used to predict the rockfill dam displacement, and the model parameters were calibrated using the triaxial experiments on scale-down rockfill samples. Due to the scale effect of rockfill material, the displacements were usually

Testing and modeling of rockfill materials: A review
Journal of Rock Mechanics and Geotechnical Engineering, 2016 AbstractThe research development of rockfill materials (RFM) was investigated by a series of large-scale triaxial tests. It is observed that confining pressure and particle breakage play important roles in the mechanical property, dilatancy relation and constitutive model of RFM.

Application of fractal theory in rockfill rheology
Shuili Shuiyun Gongcheng Xuebao, 2017 The rockfill material crushes during the process of rheology and the fractal dimension of rockfill material varies with time. Based on the basic rule of rheological process of coarse-grained soils, the fractal theory is applied into the analysis of ...

An experimental study of the behaviour of two rockfills accounting for the effects of degree of saturation [PDF]
E3S Web of Conferences, 2020 Rockfill dams have become more and more recognized for their safety, economy and adaptability to widely varying site conditions. As a contribution to the understanding of the main factors affecting the rockfill behaviour, the paper reports and discusses ...

The Role of Nature of Particles on the Behaviour of Rockfill Materials
Soils and Foundations, 2006 The nature of the particles of seven alluvial rockfill materials and three quarried rockfill materials are expressed in terms of uncompacted void content and unconfined compressive strength of each of the rockfill materials. Drained triaxial tests are conducted on modeled rockfill materials.
