Analysis of Several Lightning Accidents at the Same Time in Beijing in Combination with Lightning Location Data
Accurate and timely disaster investigation and accident analysis can help to better understand the path-ways and methods of lightning stroke.Combined lightning location data,analyzing the probability distribution of lightning in a certain area can judge and understand the law of disasters caused by lightning,which is convenient to taking more effective protective measures.This article provides a detailed analysis of three lightning accidents that occurred at the same time point in Dongcheng District,Beijing on May 24,2022,restors the lightning process,ex-plores the causes of lightning stroke,and proposes relevant solutions to reduce or avoid similar lightning disaster ac-cidents in the future.Through the statistical analysis of lightning stroke data in the Doingcheng and Xicheng districts of Beijing in recent years,it is found that the overall direction of lightning stroke was mostly in old river channels or approximate water levels,which were wet or high water levels,the soil resistivity under their buildings was relatively low,and that especially in the area of northern moats,lightning accidents occured to some extent every year.We believe that although the above laws of lightning stroke are in the urban areas of Beijing,they are quite universal,so they are of great reference value for lightning protection and fire prevention.The lightning disaster protection of surrounding modern buildings and old buildings should be given sufficient attention,and it is necessary to conduct regular and comprehensive lightning protection tests on them.
