FREQUENCY DOMAIN IDENTIFICATION OF LAYERED FOUNDATION PARAMETERS

On the basis of analysis of the movement characteristics of horizontal layered foundation and the relationship between soil parameters and eigenvalues and eigenvectors of the soil system, frequency domain identification method of the layered foundation parameters is suggested by correcting the deviation between the measured soil data and theoretical calculation results.In addition, the frequency identification process of the layered foundation parameters is performed by using the data from foundation model experiment. The result shows that the method can yields good estimate of the layer foundation parameters.
