| Abstract: | The evaluation of ground motions for diffusion earthquake is one of the important problems in the determination of site specific design basis ground motion for nuclear facilities. Therefore the estimation of near-field ground motion for small and moderate earthquakes becomes a basic research problem. Some ground motion attenuation relations are analyzed and discussed on the suitability for the estimation of near-field ground motion for small and moderate earthquakes comparing with some near-field acceleration records for small and moderate earthquakes, and then the basic idea and principle aresuggested for the estimation of near-field ground motion for small and moderate earthquakes based on the results of analysisand discussionon the suitabilityof attenuation relations and the engineering experience for earthquake problemresolution of serial nuclear facilities. |
