对滚球法计算雷击防护范围的改进

Improvement of Calculating Lightning Protection Range by Rolling Sphere Method

摘要: 基于最少时间最大概率原理,定量分析当雷暴云在高层建筑物附近移动时落雷点以及落雷区域的概率分布,提出临界高度(Zr)、临界半径(ρr)以及概率系数(Er0)的概念。在此基础上,给出高概率落雷区域划分指标,即:Er0>1的区域为危险区域,E

Abstract: According to the maximum probability theory, the probability distribution of lightning point and region is quantitatively analyzed when the thunderstorm is moving near the high-rise buildings. The concepts of Cri
