摘要
为了找出支模脚手架高处坠落事故致灾因素间的内在联系与层次结构,在通过事故调查法构建了包含13个致灾因素体系的基础上,采用决策试验与评价实验法(DEMATEL)构建综合影响矩阵,对因素体系进行了原因集合与结果集合的分类,采用解释结构模型法(ISM)对各因素间复杂的逻辑关系进行级别分配,构建了8层递阶结构模型.混合建模结果表明,引起事故发生的致灾因素可归纳为基础性因素、间接因素与直接因素,其中安全教育及制度缺乏和安全文化氛围缺失为重要的基础性因素,应急救援行动失败、架体出现局部或整体坍塌为关键性直接因素.
In order to find out the inherent connection and hierarchical structure between the caused factors for the high falling accident from the formwork falsework,based on the system including 13 caused factors established with the accident investigation method,the comprehensive effect matrix was established with the decision making trial and evaluation laboratory(DEMATEL),and the classification of both reason set and result set was carried out with the factor system.In addition,the level allocation for the sophisticated logical relations among various factors was performed with the interpretive structural modeling(ISM),and the eight-layer hierarchical structure models were established.The results of hybrid modeling indicate that caused factors which leading to the accident can be attributed to the combined action outcome consisting of fundamental factor,indirect factor and direct factor.Furthermore,the deficiency of security education,institution and security culture atmosphere is the important fundamental factor,and the failure of emergency rescue action as well as the partial or entire collapse of frame body are the critical direct factors.
