摘　　要：采用宣城市2010-2018年ADTD型闪电定位系统监测的闪电资料,经质量控制后,利用Excel、VBA编制小程序统计小于1类、2类、3类防雷建筑物滚球半径对应的雷电流幅值概率,结果表明,宣城市建筑物按照规范1类、2类、3类防雷类别设计时,其绕击率分别为0.02%、0.44%、5.94%。因此,针对不同防雷类别,可利用plot函数绘制雷电绕击率区划分布图,以期为防雷减灾工作提供科学依据。Using Xuancheng city from 2010 to 2018,ADTD lightning lightning positioning system monitoring data,after quality control,using Excel and VBA to compile a small program to calculate the probability of lightning cur rent amplitude corresponding to the rolling radius of type 1,type 2 and type 3 lightning protection buildings,it is con cluded that when the buildings in Xuancheng are designed according to the type 1,type 2 and type 3 of the code,the around rate is respectively 0.02%,0.44%and 5.94%.According to different types of lightning protection,Plot func tion is used to plot the partition distribution of the shielding failure rate due to lightning stroke,It provides scientific basis for lightning protection and disaster reduction.
