摘要
为探究高海拔地区建筑工人不安全行为认知影响因素的内在关系,建立了多层递阶结构模型;从建筑工人个体生理、心理、能力素质和建筑企业组织管理因素4个方面构建高海拔地区建筑工人不安全行为认知影响因素指标体系,采用Grey-DEMATEL模型计算各影响因素的影响度、被影响度、中心度以及原因度,采用ISM模型构建多层递阶结构模型,分析各因素对建筑工人不安全行为认知的影响。结果表明:在高海拔地区,建筑工人的安全意识对其不安全行为认知的影响程度最大;建筑工人的记忆能力、思维能力、注意能力、安全态度、施工技能为直接影响因素;建筑企业制定的安全管理规章制度为根源影响因素。
In this paper,in order to explore the internal relationship among the cognitive factors affecting the unsafe behavior of construction workers in high altitude areas,a multilevel,hierarchical and structural model was constructed.The index system of cognitive factors for construction workers'unsafe behavior was established from the four aspects of physiological,psychological,and ability quality of individual construction worker,and organization and management factors of construction enterprise.The Grey-Decision-making Trial and Evaluation Laboratory model was used to calculate every factors'influence degree,influenced degree,centrality degree and the reason degree,and the Interpretative Structural Modeling Method model was used to construct the multilevel,hierarchical and structural model,so as to analyze the cognitive factors affecting the unsafe behavior of construction workers in high altitude areas.The results show that the safety awareness of construction workers has the greatest effect on the cognition of construction workers'unsafe behavior;that memory ability,thinking ability,attention ability,safety attitude and construction skills of construction workers are the direct influence factors;that the safety management rules and regulations formulated by construction enterprises are the root influence factors.
