Vyzhva S. Theory and methodology of the complex geodynamic interpretation of the geophysical monitoring data of dangerous geological processes.

The thesis is devoted to the theory and methodology development of complex geodynamic interpretation of the geophysical monitoring data of dangerous geological processes on the basis of the fractured geological environment nonlinear multicomponent anisotropic model. The analysis of dangerous geological processes of current state and the evolution prevention on the territory of Ukraine is provided and approaches concerning complex geodynamic interpretation of the data are developed on the basis of a geophysical tomography methods, the technology of seismic-acoustic monitoring is suggested. The mathematical modeling of acoustic and elastic characteristics of the multicomponent geological environment with cracks orientation arbitrary function (sandstone model) and an anisotropic matrix (amphibolites model) is developed on the basis of the generalized method of imaginary moment functions. The method of numerical computation of multicomponent anisotropic fractured environment an effective thermoelastic properties is developed. Modeling of pressure and temperature effect on speed of elastic waves (peridotite model) and thermoelastic characteristics of an oceanic top mantle mathematical modeling are performed. Modeling of effective nonlinear elastic constants of fractured quartz sandstone with different parameters of interstices filling is performed. Acoustically elastic effects in the geological environment and distributions of elastic waves in the environment with initial pressure are investigated. Methods of statistical modeling application of random processes and fields for the problem decision of predication parameters definition with an incomplete network of geophysical supervision are developed. Research of a state and the forecast of karst-suffosion processes evolution on the Rivne Nuclear Power Plant site till 2006 is performed.
