The basis of seismic micro-zoning of the construction site of the Zheleznogorsk OIAE is the interaction of two models - a model of seismic sources of earthquakes and a model of the seismic effect based on the frequency of earthquakes in the region under consideration, which determine the spatial and temporal distribution of seismicity. Probabilistic analysis of seismic hazard in the region reduces to the creation of a synthesized catalog of earthquakes for a predetermined period of time with a fixed repeatability, depending on the removal of the object from the source in increments of magnitude. The calculation of seismic intensity was carried out on the basis of geological and seismological information about the object, as well as soils on the 3D model using the seismic rigidity method. The synthesized catalog of earthquakes is constructed for the standard periods of recurrence of 1000 years (PZ) and 10,000 years (MW) based on WHO area and linear zones and a set of statistics on the number of concussions of different intensity and frequency that determined the calculated peak accelerations and amplitudes of the generalized reaction spectra for different periods of recurrence. The correlation of the calculated intensity and duration of seismic oscillations at the site on medium soils is established. The synthesized model initial 3-part accelerogram corresponding to the synthesized earth-shaking catalog was constructed according to the RB-006-98 technique, the numerical modeling of the ground reaction to seismic actions was determined by the program (WinShake) for different levels from 7 to 8 MBK MSK-64 points in vid de accelerograms, bicycles and seismograms.
