| Zusammenfassung: | The invention relates to a method for analyzing nonlinear characteristics of geotechnical materials. The method comprises the specific steps of: (1) acquiring observation data, wherein massive observation data is obtained from a seismic monitoring system, and the observation data is processed by adopting a Fourier transform method to obtain a three-directional response spectrum curve; (2) drawing a site average amplification response spectrum curve, wherein site amplification response spectrum curves are calculated according to the three-directional response spectrum curve in the step (1), and the site average amplification response spectrum curve is calculated and drawn; (3) calculating a modulus decrease ratio, wherein main influencing frequencies of a stratum are analyzed according to the site average amplification response spectrum curve drawn in the step (2), the modulus decrease ratio is calculated and the nonlinear characteristics of the geotechnical materials are analyzed.
