Research On Influence Of Construction Workers' Risk Tolerance On Unsafe Behaviors

As one of the pillar industries of the national economy,the construction industry is characterized by personnel-intensive,long cycle,large volume and complicated and changing production environment.these factors lead to a variety of risks in the construction process,which cause frequent accidents in the construction industry,leading to lower safety performance of construction enterprises.At the same time,due to the larger cost of construction projects investment,the impact of a wide range,many minor mistakes will cause unexpected heavy losses.Among the many factors that affect the safety performance of the enterprise,the unsafe behavior of the workers is one of the main direct causes of the accident.Therefore,the elimination of workers' unsafe behavior is an effective means to improve the safety performance of construction.The root cause of unsafe behavior is cognitive failure,and the frequency of unsafe behavior caused by failure of choice is the highest and the mechanism is most complicated.If you can get a better understanding of the behavior of the implementation of the main body on the degree of tolerance of risk behavior,clear and cognitive factors between the mechanism of interaction and the final behavior of the mechanism of action,and accordingly take measures to reduce the risk of construction workers tolerance,for the construction site Improve the performance of security behavior has an important role.This paper first defines the risk tolerance of construction workers by summarizing the main theories of unsafe behavior and behavior.and points out that people's unsafe behavior is the main cause of safety accidents,people's unsafe behavior and accidents The construction workers as a behavioral decision-maker is bounded rational,and in the production process is bound to appear irrational behavior,and individual psychological factors such as risk tolerance will be through the attitude,behavior control perception and The interaction of subjective norms ultimately affects the individual's will and behavior.Then,the paper divides the relevant experts and scholars to divide the risk tolerance,attitudes,subjective norms and behavior control perception of the construction workers through the literature research.The attitudes are divided into the comparison of risk comparison and convenience.The subjective norms are divided into managers' influence and workers Influence,behavior control perception is divided into self-efficacy and external conditions;and on this basis,combing the literature,mining scholars on the construction workers risk tolerance,behavioral cognitive factors and behavioral will,behavior-related links,put forward the hypothetical path and build Initial structural equation model.Through the questionnaire of risk tolerance and unsafe behavior of construction workers,SPSS software and AMOS software were used to verify the data and the initial model,and the theoretical knowledge was corrected until the model fit was good.In this paper,we focus on the research object,that is,the personality trait factors of construction workers do not directly affect the final behavior choice,but indirectly affect the behavior choice by influencing the behavioral intention,and And the willingness to act have a significant negative impact effect,that is,the construction workers themselves,the lower the risk tolerance,the more willingness to take security behavior.At the same time,the risk tolerance of construction workers in some key pathways is influenced by subjective normative factors,and plays a mediating role in the influence of final behavior selection.Finally,according to the research conclusion,the corresponding countermeasures and suggestions are put forward.First of all.it is necessary to pay attention to the personality factor of construction workers' individual risk tolerance.Because the individual risk tolerance has a significant negative effect on the willingness of the security behavior,it can effectively reduce the risk tolerance of the construction workers,and can significantly enhance the safety risk consciousness and the correct risk coping concept and reduce the probability of accident occurrence.Second,we should also give the same attention to the influence of managers and the impact of workers.On the site managers,such as the foreman should have a complete construction safety knowledge and skills,and in the exchange of feedback with the workers to highlight the correct security attitude;construction workers groups,should play a technical backbone and safety model of the exemplary role,At the same time in the process of workers to cooperate,to strengthen the construction workers awareness of the group,so that the same operation in the process of mutual care,mutual concern,the formation of a good safe construction atmosphere.The innovation of this paper is as follows:(1)Through the collection of relevant data analysis,from the perspective of the concept of psychological risk of risk tolerance,to explore their impact on construction workers unsafe behavior mechanism.(2)The mechanism of risk tolerance and behavioral cognitive factors acting on behavioral will and behavior is established,and the empirical study is used to test and revise,and the research system of unsafe behavior of existing construction workers is supplemented and perfected.
