Abstract
The large size of the particles in rockfill structures prevents the appropriate laboratory testing. Moreover, the humidity is a key point to explain changes in the long term deformability of rockfill. Therefore, prediction of field behavior requires the development of models that integrate size effects and humidity changes. The Distinct Element Method has been used to develop a numerical model that includes assemblies of several spherical particles in a pyramidal shape. These "macroparticles" br...
