Engineering Properties of Wet-Pluviated Hollow Cylindrical Specimens
A hollow cylinder apparatus was used to study some engineering properties of hollow cylindrical sand specimens prepared using the wet-pluviation technique. The refined specimen preparation method had good repeatability. Wet pluviation produced inherently cross-anisotropic specimens, with the initial level of anisotropy reducing with decreasing initial void ratio. The variation in the initial void ratio of the sand specimens was related to the volume of the specimens. The stress-strain responses under isotropic consolidation were not significantly affected by the small variations in the initial void ratios that occurred for a target initial specimen volume. The levels of membrane penetration recorded for the different specimens were independent of the applied cell confining pressure, and the amount of membrane penetration compared well with other experimental studies.
