Annotation:
One of the possible options to decrease seismic response of NPP resting on a rocky site is to set a «pillow» (filled with comparatively soft soil) under a base mat. However, seismic analysis of such a foundation by means of SASSI code meets certain problems. The author demonstrates these problems and suggests the way to solve them.
