针对隧道工程施工安全问题,从隧道工人行为角度出发,结合问卷调查数据,建立分层线性模型(hierarchical linear model,HLM),从微观上解释了安全行为关联因素影响过程.利用信效度评价检验了309 份有效数据的可靠性,通过假设检验依次分析了隧道工人群体安全行为对个体安全行为、安全氛围以及团队效能的影响作用.结果表明,群体安全行为对个体安全行为具有显著正向影响;安全氛围在群体安全行为与个体安全行为之间具有中介作用;团队效能在安全氛围与个体安全行为之间具有正向调节作用.以上结果为更好地发挥安全行为在隧道施工安全管理中的作用提供了指导.
Influence of Tunnel Workers'Group Safety Behavior on Individual Safety Behavior
In response to the safety issues in tunnel construction projects,a hierarchical linear model(HLM)was established from the perspective of tunnel workers'behavior,combined with questionnaire survey data,microscopically explaining how factors related to safety behavior affect the process.The relia-bility of the 309 valid data was tested using criterion-related validity evaluation,and the hypothesis testing was used to analyze the impact of group safety behavior on individual safety behavior,safety climate,and team effectiveness among tunnel workers successively.The results show that group safety behavior has a significant positive effect on individual safety behavior;safety climate has a mediating effect between group safety behavior and individual safety behavior;team effectiveness has a positive moderating effect between safety climate and safety behavior.The results above provide guidance for better utilizing safety behavior in the management of tunnel construction safety.
