The dynamic response of a saturated layered soil deposit was modeled on the Princeton University geotechnical centrifuge using various centrifugal acceleration levels. The layered soil deposit consists of a saturated Nevada sand layer overlaid by a silt layer of low permeability. Measured acceleration and pore-water pressure time histories are used to validate the scaling laws used in interpreting dynamic centrifugal modeling test results. Careful measurements of the settlements at the silt surface are performed using a non-contact displacement transducer, and comparisons are made with measurements obtained with a standard linear voltage displacement transducer. Finally, the experimental results are used to verify the validity of the numerical procedures encompassed in the computer code DYNAFLOW.
