Research On Safety Accident Model Of Construction Based On Data Mining

Construction safety accidents cause great losses to the lives and property of the employees.How to comprehensively and effectively identify,control and prevent the risk factors in the construction site is a major problem facing the safety management of the construction industry.In this paper,the safety accident data to data mining and safety accident report text data,using the theory of system analysis and cause analysis,build the explanation structure model,the cause of countermeasures,to step by step a multi-level reason existing in the safety accident analysis,to explore the inherent law of safety accidents occur,classification and analyze the deep reason of possible,to find the corresponding countermeasures.First of all,by collecting data of exploratory data analysis,found that the safety accident in time,place,type of accident and other related information,then use the text mining induced 22 cause elements,with the method of visual display,the application of the theory of system analysis,build the explanation structure model,the building construction safety accident reason is divided into three levels,Safety management analysis is carried out on the factors at each level,which reflects the internal correlation from the surface to the deep.Comprehensive data characteristics of the construction safety accident,text mining and relevant keywords co-occurrence analysis,finally from the aspects of technology,management,and other building construction safety accident prevention countermeasures and Suggestions,through the engineering to put forward corresponding proposals,help from the system and implementation level to ensure the safety of construction,for it may serve as a reference for the construction safety accident prevention,It can help the construction industry to reduce casualties and property losses,effectively protect the life and health of construction practitioners,and contribute to the establishment and smooth operation of the long-term mechanism of construction safety accident prevention.
