摘要
为了解决高校建筑群防雷系统保护性比较脆弱的问题,采用主成分分析法对避雷系统进行了安全评价。以某高校为例,将校区分为教学区、宿舍区、办公区及实验楼4个子系统,从避雷系统的单项构件和环境因素方面共16个因素进行了分析,并采用SPSS统计软件进行了计算。分析结果显示,教学区的得分最高,即避雷系统的保护作用最差;防雷电感应方面的措施有待改进;环境因素在避雷系统中有很大影响。
In order to solve the problem that lightning protection systems of building groups in campus are quite weak,safety of lightning protection system was assessed using principal component analysis method.The study took a university for example,whose campus was divided into four subsystems: teaching plot,dormitory plot,office plot and experimental buildings.The building group was analyzed from 16 factors extracted from single component lightning protection system and environment and calculated by statistic software SPSS.The results indicated that the teaching plot get the highest score,meaning a weakest protection system;lightning induction prevention is to be improved;and environmental factors have great influence on the lightning protection system.
