摘要
为探究影响建筑工人安全能力的因素,提出一种集成解释结构模型(ISM)与序相关法(G1-Method)的因素分析法。首先,基于壳层模型(SHELL)与因子分析法,归纳与提取影响因素;其次,通过ISM构建工人安全能力影响因素多级递阶结构模型;最后,结合改进的G1-Method,计算因素间关联度及对安全能力的影响重要度。结果表明:所构建的安全能力影响因素结构模型包括安全认知能力、安全行为能力2个维度,以及16个影响因素。其中,安全观念、操作技能、环境适应是建筑工人安全能力形成的浅层因素,而安全教培、安全管理是安全能力形成的深层因素。同时,安全观念、安全教培、环境适应是安全认知能力的主要影响因素;操作技能、安全教培、安全管理是安全行为能力的主要影响因素。
To explore the factors affecting the safety competency of construction workers,a factor analysis method integrating ISM and G1-Method was proposed.Firstly,the influencing factors were summarized and extracted based on the software-hardware-environment-liveware-liveware(SHELL)model and factor analysis method.Secondly,the multi-level hierarchical structure model of influencing factors of workers'safety competency was constructed through the ISM.Finally,the G1 method was used to calculate the degree of correlation between various factors and the importance of their impact on safety competency.The results show that the constructed model of the influencing factors of safety competency includes two dimensions of safety cognition competency and safety behavior competency and 16 influencing factors.Among them,safety concepts,operation skills and environmental adaptation are the superficial factors for forming construction workers'safety competency,while safety education and management are the deep factors for forming safety competency.At the same time,safety concepts,safety education and training and environmental adaptation are the main influencing factors of safety cognition ability.Operation skills,safety education and training and safety management are the main influencing factors of safety behavior competency.
