Research On Emotion Induction Mechanism And Empirical Study Of Unsafe Behavior In Metro Construction

At present,our country is in the period of rapid development of metro construction.The speed and scale of metro construction in major cities are unprecedented.The achievements of metro construction are accompanied by a large number of safety accidents,and the number of accidents is increasing year by year.Unsafe behavior of metro construction workers is the most important factor in the accident,and there are many factors behind the unsafe behavior of metro construction workers.In the study of influencing factors of unsafe behavior in metro construction,many conclusions point out that emotion have an important impact on workers' unsafe behavior,but the study on the relationship between emotion and unsafe behavior has not attracted enough attention.Therefore,from the emotion point of view,analyzing the emotional action paths of unsafe behaviors in metro construction,identifying the influencing factors of workers' emotions and studying the evolution laws of unsafe behaviors in metro construction under the influence of emotions are helpful to improve the performance of workers 'unsafe behavior management.On the basis of literature analysis,the effect of emotion on the unsafe behaviors of metro construction workers was analyzed in this paper,and the affecting factors of emotion were also discussed.A model of emotional factors of unsafe behavior in metro construction from two emotional action paths of anticipated emotion and incidental emotion was constructed,the effect of anticipated emotion and incidental emotion was compared by using structural equation model.And the influencing factors of negative incidental emotion are empirically analyzed.Then,based on the influencing factors of negative incidental emotion,the evolution model of unsafe behavior induced by negative incidental emotions is constructed by using system dynamics method,and the evolution process of unsafe behavior under the influence of negative immediate emotional factors is analyzed.Finally,through the data acquisition platform composed of video surveillance system,sound level meter and negative incidental mood scale,the data of unsafe behavior level,site noise and workers' negative incidental mood level in a metro station are collected and processed,which verifies the influence of site noise on unsafe behavior in the actual construction process.The main conclusions based on the research process of this paper are as follows: the main type of emotional effect on unsafe behaviors in metro construction is negative incidental emotion.The negative incidental emotion has stronger and more significant effects on unsafe behaviors than the feedback and regulation of anticipated emotion.The noise of construction site is a very important factors for both negative immediate emotion and unsafe behavior.In the safety management of metro construction,it is necessary to strengthen the noise control measures.
