Abstract :
Relations of nonlinear processes of seismic wave radiation by a ground-based vibrational source and their ldquoaccumulationrdquo during the propagation of waves in the medium are considered. Results of numerical modeling of the dependence of the parameters of seismic wave field nonlinearity on the characteristics of mediumpsilas inhomogeneity are presented. Fluid-saturated fractured media with different parameters of physical elasticity are considered as examples.
