【摘要】 提出了一种利用潜源区样本空间确定空间分布函数的思路—潜源区样本空间法。除潜源区和地震目录外,不需要任何额外的资料,该方法就可以给出4套不同的空间分布函数,还可以提供任意震级间隔的空间分布函数,不存在多因子方法中因子分辨率与计算震级档不协调的问题,更好地体现了潜源区之间地震活动的空间差异,适用于多方案潜源区开展概率地震危险性分析。更多还原

【Abstract】 This paper introduces a new approach,called source-sample-space method( SSSM),to estimate the spatial distribution functions by means of the source sample spaces. This method can provide four different spatial distribution functions for every seismic zone,without any necessity of additional data but the sources and catalogue. It can also give the spatial distribution functions for any interval of magnitude and will not suffer from a simple mismatch existing in multi-factor method: the intervals of magnitude suited to the factors are always too large to be suitable for computation of seismic risk,so more obvious spatial differences in seismic activities between potential sources can be reflected. The calculating of SSSM is very simple,so SSSM is most practical,especially suitable for the implication of probabilistic seismic hazard analysis when using multi- scheme sources.更多还原
