| The safety issue is a major concern of the society,especially in the field of engineering construction,construction safety is particularly sensitive.With the development of society and the advancement of technology,the degree of early warning of the safety management of construction projects in China is getting higher and higher,and the previous post-event control and event control gradually shift to prevent beforehand.However,most construction projects still have problems of imperfect warning system and imperfect warning mechanism.If the construction industry can have a healthy and orderly development prospect,it is necessary to improve the construction safety management early warning mechanism and advance the construction safety impact factors.Find it out and minimize the harm it poses.Therefore,it is of great theoretical and practical significance to establish and improve the early warning system and mechanism for safety management of construction projects.From the perspective of construction projects,this paper first analyzes the research status of construction construction safety early warning management at home and abroad,and introduces related theories such as construction project safety early warning management and accident cause,from people,materials,management and environment and technology.These five aspects have found out the main influencing factors of construction safety accidents,and comparative analysis of existing safety early warning methods.Secondly,on the basis of this,fuzzy theory and analytic hierarchy process are used to establish a security early warning model based on fuzzy analytic hierarchy process and the feasibility of the model is expounded.Then,the article designs the safety early warning index system of construction projects,and optimizes the index system through expert consultation method and theoretical analysis method.Finally,the construction safety warning management of construction projects consisting of 5 first-level indicators and 30 second-level indicators is constructed.Indicator system.Finally,taking the NJ construction project as an example,the paper applies the established safety early warning model and the designed early warning index system to the actual engineering project,and carries out safety evaluation on the NJ construction project,and proposes relevant countermeasures based on the evaluation results. |
