“BELENE” Nuclear Power Plant: numerical and experimental free field signals

Investigation of “BELENE” Nuclear Power Plant (NPP) free field signals is presented. The SH wave propagation through multilayer geological media in the region is considered. The original structural model of the geological column is developed. The layers are isotropic, with a constant depth and parallel skyline. The SH rays are with an arbitrary angle regarding the layers. The seismic SH waves are generated by a special detonation device. The main results of the study are graphically illustrated. The comparison between the original “BELENE” NPP experimental and the numerical surface (free field) signals (obtained by the direct problem, formulated in Section 4) for the investigated geological column is made.
