摘　　要：为了贯彻“预防为主,防治结合”的科学理念,实现安全可靠、技术先进、经济合理的综合性防雷设计,精确细致的防雷级别判定工作是做好古建筑群防雷保护的重中之重。该文给出一种古建筑群的等效雷击截受面积的计算方法,并以属于省级重点文物保护单位的某古建筑群的防雷级别判定为例,计算古建筑群预计年均受雷击次数,可实现其防雷等级的判定,对古建筑群做一个精确细致的防雷级别判定,为同类古建筑群的防雷等级判定提供参考。In order to implement the scientific concept of"prevention first,prevention with control combined",and achieve a safe,reliable,technologically advanced,and economically reasonable comprehensive lightning protection design,precise and detailed lightning protection level determination is the top priority for lightning protection of ancient building clusters.This article provides a calculation method for the equivalent lightning strike cross-sectional area of ancient building complexes,and takes the lightning protection level determination of a certain ancient building complex belonging to a provincial-level key cultural relics protection units as an example to calculate the expected annual lightning strike frequency of the ancient building complexes,achieving its lightning protection level determination.An accurate and detailed lightning protection level determination is made for the ancient building complexes,providing a reference for the lightning protection level determination of similar ancient building complexes.

关 键 词：古建筑群 等效雷击截受面积 防雷等级 判定方法 预计年均受雷击次数
