建筑安全事故与时间关系探讨

Discussion on the Relationship Between Building Safety Accidents and Time of Day

为了探究施工事故类型与时间的关系,文章利用爬虫爬取2012~2018年建筑安全施工事故类型成因数据共3896条,建立了施工安全事故中各种类型与事故发生时间的列联表,利用对应分析,建立出了Q型因子分析与R型因子分析的关系。通过特殊点剔除法对模型收敛性优化,最后将模型中的施工安全事故类型的成因与一天的时间绘制在二维模型对应的分析图中;根据图中的关系挖掘两者之间的关系。以3896条建筑安全线路发生事故的数据采集情况为主要分析依据,提出事故主成因分析挖掘的办法,结果得出:车辆伤害与晚上8点到9点这一时间段联系紧密,凌晨5点到6点与火灾和爆炸发生紧密联系。并为建筑事故预防提出相关建议。

To explore the relationship between the type and time of construction accident.In this paper,reptiles crawling 2012-2018 Building construction safety accident causation total 3,896 types of data,the establishment of various types of contingency tables with the accident construction safety accident time,with the corresponding analysis,a Q-mode factor analysis R-type relationship with the factor analysis.Convergence of the model optimized by the special points out method,and finally causes of accidents in the model type of construction and plotted against time of day in the two-dimensional model corresponding to FIG analysis;Mining relationship between the relationship of FIG.To 3896 construction safety line data acquisition event of an accident as the main analytical basis,it puts forward the main causes of the accident analysis approach to mining,result:vehicle damage in close contact with the night from 20 to 21:00 time,5:00-6:00 with fire and explosion the occurrence of close contact.And recommend ways of preventing prevention for the construction ac cident.
