Inversion Uncertainty in Surface Wave Analysis

摘要: This study deals with uncertainties associated to solution non-uniqueness in surface wave analysis, special attention the influence of maximum available wavelength experimental data. Typically, it is assumed that investigation depth about half dispersion curve. In order assess validity this assumption, three different datasets (one synthetic and two real world case histories) have been analyzed a Monte Carlo approach. Low frequency data progressively scalped consequences on reliability solution. For selected histories, reasonable estimate average parameters obtained limited amount information. Nevertheless, risk reaching local minimum inversion process availability The use global search method has be preferred as they can provide an
