摘要:
根据雷暴数据统计资料和雷电风险评价闪电定位资料，采用统计分析和相关雷电防护标准，对肇庆市伴月湖社区体育公园雷击风险进行了定性分析与定量计算。结果表明：伴月湖社区体育公园区域7月雷电闪击的概率最多，19：00出现的闪电频数最高，雷电流最大值为117.5kA，3km范围内地闪密度值Ng为14.84次/（km2·a）。人员处于无雷电防御设施的封闭建筑物、敞开构筑物内，风险分量总和低于风险容许值1×10-5；大树底下、露天场所风险分量总值高于风险容许值1×10-5，是公园雷击人身伤亡的主要区域。按照相应类别采取防雷措施后，封闭建筑物区和敞开构筑物区风险分量RA各降低了99%。人员及时进入防雷设施合格的建筑物内，风险分量可降为0。
Abstract:
Based on the statistical data of thunderstorm and lightning location data of lightning risk assessment, this paper used statistical analysis and related lightning protection standards to make a qualitative analysis and quantitative calculation on the lightning strike risk of the Banyue Lake Community Sports Park in Zhaoqing. The results showed that the probability of lightning flashing in July was the most,the lightning frequency at 7 pm was the highest,the maximum value of lightning current was 117.5 kA, and the value of flash density in the 3 km range (Ng)was 14.84 time/(km2 ·year). In the closed buildings and open structures without lightning protection facilities, the total risk components were lower than the risk allowable values of 1×10-5, the risk components under trees and open air places were higher than the risk admissible values of 1×10-5, which were the main areas for personal injury in the park.After taking lightning protection measures according to the corresponding categories, the risk component (RA) of enclosed building areas and open structures decreased by 99%. What is more, when a person enters a building qualified for lightning protection in time, the risk component can be reduced to 0.
