concrete gravity dams & Centrifuge tests

Despite limited experimental data, the reported tests are the first in
which uplift measurements have been made for a concrete dam in a
centrifuge; a special concrete mix with sufficient permeability was
developed to model a pervious foundation. The know-how to per-
form these complex tests has been refined, and is currently exploit-
ed in other tests performed under the auspices of the Tokyo Electric
Power Company (TEPCO) on the centrifuge facility of Obayahi
Corporation where a dam model is mounted on a shaking table
installed in a centrifuge. Finally, those tests enable the validation of
the authors’ finite element code (Merlin) to correctly model static
nonlinear dam response with uplift and crack opening
