摘要
Abstract
In this paper,the seismic risk analysis of a site in Shandong was carried out by using the method of CPSHA.The field was divided into potential source areas,seismicity parameters,seismic attenuation relationship,seismic risk probability analysis.The results determined the major contribution to the peak acceleration of ground motion of several potential seismic source and theirs contribution values,and the 50 years beyond the probability 10％ level to the peak acceleration of ground motion.It turned out that,the CPSHA method divided the potential source regions with specific tectonic scales and more detailed structural markers,so it greatly reduced the size of potential focal regions and reflected the in homogeneity of the spatial distribution of seismic activity.关键词
