摘要
通过近十余年雷击古树名木的现场勘查,对雷击古树名木的危害机理进行分析研究,提出采用不同类型的接闪装置对单株、多株古树名木实施防雷保护的技术要求和方法,并对防雷装置的设计与安装、安全护栏、警示标示的设置、接地装置的埋设深度等提出具体要求。实施古树名木的雷电防护,对保护古树名木的正常生长存活,维系生态平衡,提高防雷管理技术水平,具有重要的现实意义。
On the basis of on-site inspection of more than 10 years, and through analyzing damage mechanism of lightning on ancient and heritage trees, the technical requirements and methods for lightning protection through dif-ferent air-termination system for individual or several trees were proposed.The specific requirements for design and installation of lightning protection device, setting of safety barrier and warning mark, burying depth of earth-termi-nation system, were put forward.It is meaningful to implement the lighting protection standard of ancient and her-itage trees for these trees’ surviving and normal growth, maintaining ecological balance, and improving lightning protection technology.
