基于模糊数学的重庆地区雷电灾害风险评估方法研究
Research on the Lightning Risk Assessment Method for Chongqing Based on Fuzzy Mathematics
摘要
Abstract
Reasonable and scientific lightning disaster risk assessment can effectively reduce losses caused by lightning, but at present the lightning risk assessment system is not perfect, sometimes it cannot well evaluate actu-al lightning disaster risks.For some certain occasions, IEC62305-2 standard dose not well reflect the true lightning risk, such as large-scale residential district, a large area factory, etc.In these cases, on the basis of in-depth stud-y on the mechanism of lightning disaster, the lightning risk can be analyzed by three aspects of hazard, exposure and vulnerability of hazard bearing body.By AHP and fuzzy mathematics theory, the lightning risk assessment for-mula for Chongqing region is obtained.Through the lightning risk assessment method specific assessment verifica-tion shows that this method has better applicability and can better serve lightning protection and disaster reduction in Chongqing region, and it can be a good supplement for IEC62305-2 lightning risk assessment.关键词
