The identification algorithm consists of: (1) evaluation of strain time histories from the motions recorded by a multi-dimensional array of closely spaced accelerometers, (2) estimation of stress tensors corresponding to the evaluated strains, (3) computation of accelerations associated with the estimated stresses, and (4) evaluation and calibration of an optimal model of soil response by minimizing discrepancies between the recorded and computed accelerations. Computer simulations and experimental data analyses showed that the proposed technique provides an effective tool to identify local soil characteristics and properties.
