The void distribution of specimens of Ottawa sand was quantified
via Magnetic Resonance Imaging (MRI) technique. Two specimen
reconstitution techniques, wet-tamping and air-pluviation, were
used to generate the specimens. The specimen was prepared in a
non-metallic triaxial cell. After fully saturated, the specimen
with the cell was put inside a MRI device. Data was acquired at
initial state and different stages of the conventional drained
triaxial compression test. The acquired MRI data gives a direct
measurement of the fluid phase in the voids, thus providing a
complete picture of the local void distribution in saturated
specimens. Programs written in Interactive Data Language (IDL) were
used to implement the automated image processing and analysis from
the collected MRI data. The initial uniformity and the evolution of
voids during the drained triaxial compression test were
investigated. The presented results provided a critical assessment
of the specimen reconstitution techniques and a better
understanding on the mechanisms of the localized deformation and
failure of granular soils.
