Estimation of spatial deformations of the Earth-crust in the Ignalina nuclear power plant region by applying the data of GPS monitoring

Abstract

Spatial Earth-crust deformations have been assessed by finite element method, the algorithm for determining deformations has been compiled. Experimental analysis has been carried out on the site of Ignalina Nuclear Power Plant geodynamic polygon. The new spatial Earth-crust parameters of deformations have been received - spatial relative linear and shear strains. The results of the research indicate that spatial Earth-crust deformations signify themselves by certain regularities, namely the Earth- crust movements in the ares of Ignalina Nuclear Power Plant are differentiated in accordance with the blocks: northern and southern.
