摘　　要：地震危险性计算是山西省地震灾害风险普查工程的基础工作内容之一,文章基于概率地震危险性分析方法对山西省地震危险性进行计算。简述地震危险性计算的原理、数据处理与图件制作流程,将计算结果与第五代地震区划图潜源模型的计算结果进行对比分析,结果表明基于风险普查潜源模型的晋西北、晋东南山区计算结果稍有增大;汾渭断陷带内的计算结果略有降低,但差距很小,可认为结果基本一致。同时对产生差异的原因进行初步分析。Seismic hazard calculation in Shanxi Province is a fundamental aspect of the seismic hazard risk assessment project.This article employs probabilistic seismic hazard analysis methods to calculate the seismic hazard in Shanxi Province.The study briefly outlines the principles of seismic hazard calculation,data processing,and map production processes.It compares the calculated results with those from the fifth-generation seismic zoning map's source model,analyzing the discrepancies.The findings indicate slight increases in the calculated results for the northwestern and southeastern mountainous regions of Shanxi based on the risk assessment source model,while results within the Fenwei Rift Zone show marginal decreases,suggesting overall consistency.And conduct a preliminary analysis of the reasons for the differences.
