A combined analytical/experimental study entitled 'Canister-Backfill-Medium Interaction' (CBMI) was conducted to investigate the effects of backfilling procedures on the response of ground motion instruments located in instrumentation boreholes during wave propagation experiments. The experimental portion was conducted by the U.S. Army Engineer Waterways Experiment Station (WES) and is reported herein. A companion analytical study was conducted by Agbabian Associates (AA), El Segundo, California. The analytical study attempted to calculate the measured motion-time histories by use of input load functions and material properties data. Results of the analytical effort are discussed in a separate report published by AA.
