雷电灾害风险分级方法研究
A Study on the Lightning Disaster Risk Grading Methods
摘要
Abstract
Annual mean thunderstorm days,lightning density,lightning current intensity,vital vulnerability module and economic vulnerability module are presented as grading indices of lightning disasters risk.The features of lightning current intensity accord with the synthesis of the average lightning current amplitude,probability of shielding failure and lightning strike on the basis of different rolling sphere radius.Based on thunderstorm days dur-ing 1981 ~2010,lightning location data from 2008 to 2014 and demographic and economic data in China,hierar-chy thresholds of lightning disaster risk grading indices are obtained.The classification method of lightning disaster risk is studied.Provide reference for the research and risk management on lightning disaster.关键词
