Strength and deformation characteristics of rockfill materials
Geotecnia, 1979 In the last years, some authors have found to set up rheological models for rockfill materials. This article analyses the most important literature on the subject some suggestions based on laboratorial tests performed in LNEC are made. Three questions are particularly stressed: the study of deformability based on considerations about the ...

Effect of Particle Shape and Confining Pressure on Breakage and Deformation of Artificial Rockfill
, 2019 © 2019, Springer Nature Switzerland AG. The rockfill exhibits a substantial amount of particle breakage when subjected to higher range of stresses. The deformations of rockfill under such excessive stresses often lead to failure and cannot be ignored ...

Suction effects on rockfill compressibility
A conceptual mechanism of rockfill deformation was postulated by Oldecop & Alonso (2001) on the basis of the observed rockfill behaviour in suction-controlled oedometer tests.

Modelling of shear strength of rockfills used for the construction of rockfill dams
, 2018 This paper presents the results of examination of shear properties of rockfills used for the construction of rockfill dams. Based on the results of a large number of experiments, mathematical model of the shear strength of the rockfill was derived, as a ...

Effect of loading history on time dependent deformation of rockfill
The paper explores the time-dependent compressibility of coarse crushed quartzitic slate, focusing on the effects of the previous loading history. Large diameter oedometer tests were performed at different relative humidity (or total suctions) and ...
