Collapse of rockfills

Abstract

The rockfill materials display collapse deformations due to wetting or saturation. ln this paper the quantification of this phenomenon is shown for soft and hard rockfills tested in 1-D compression and triaxial apparatus. The results pointed to more important collapse in soft rockfill, to equal final settlements obtained after saturation of dry samples or if the specimens are saturated prior to tests, and to some variation of Poisson's ratio due to saturation.
