摘　　要：通过雷击风险评估可为评估对象提供雷电防护的科学设计、危害风险控制、经济投资、应急管理等方面服务,保证防雷工程安全可靠、技术先进、经济合理。本文重点针对建筑物内部磁场强度进行评估研究,提出了直接和邻近雷击时内部磁场强度的估算方法,并给与了实例说明,完善了整个风险评估的内容,更为科学全面地保障了企事业单位的安全生产。Lightning risk assessments are the base to lightning protection and could effectively control risks and deal with emergency management.The results ensure advanced technology and economic rationality in lightning protection project. This article focuses on assessment research for the internal magnetic field intensity. Then, the estimation method of the internal magnetic field intensity of direct and nearby lightning strikes is proposed, which improve the content of the entire risk assessment, and is more scientific and comprehensive to protect production in the enterprises.
