基于主成分分析的建筑施工安全评价方法研究

本科论文AbstractWith the development of urbanization in China,the construction industry,as aneconomic pillar,is still on the upward trend.As the social demand gradually increases,thedevelopment of the construction industry will be faster.However,in the rapid developmentsituation,many construction companies of various levels appeared.Safety accidents are notuncommon when companies seek power generation and cost savings workers'safetyawareness is weak,and construction environment risks are intertwined.Under the current circumstances the safety evaluation of construction sites inconstruction projects employs a traditional safety evaluation method.Most of them onlydistinguish the safety and danger in nature.In the construction site,the safety factors arecomplex and interact,and the traditional evaluation method can not screen out the mainfactors in many safety factors.Therefore,We need to introduce quantitative methods to assessthe safety of the construction site.In this paper,the safety evaluation of the construction sitewas conducted using the principal component analysis method.Based on the analysis of the safety factors in the construction site,a construction safetyevaluation index system was established,which included 6 indicators and 28 evaluationindicators,and using safety inspection tables to provide scores and figures to experts.Weobtained the first data that entered the PCA and obtained the desired main ingredients throughanalysis.We can see the factors that have a major influence on the safety of the constructionsite.We rank the safety of the construction sector by obtaining comprehensive value throughthe component point rate table.You can tie.Through the PCA method,we can find out the main factors from several safety factors,which is conducive to the safety management of the project and the clear managementdirection.Key words:building construction;safety management;safety evaluation method safetyevaluation index system;PCA
