摘要
为充分识别建筑施工安全事故致因规律,利用复杂网络模型对建筑安全事故进行分析.根据系统思维提出了包含6个子系统和40个因素的事故致因系统;以1196份事故调查报告为数据,以致因因素和事故类型为节点,以关联规则得到的因素关联为边,以因素共现频数为边权,构建事故致因网络模型;通过复杂网络基本参数计算、节点重要程度分析,得到6项关键致因因素和3条关键致因链;通过案例分析对模型进行论证,并从工程实践的角度提出建议.
Abstract
To fully identify the causes of construction safety accidents,a complex network model was used to conduct the analysis.Firstly,an accident causal system with 6 subsystems and 40 factors was constructed based on system theory.Secondly,a network model of the causes of the accidents was constructed using 1196 accident investigation reports as data resources,causal factors and types of accidents as nodes,relationships between factors obtained by the association rule method as edges,and frequency of co-occurrence between factors as edges'weight.Thirdly,6 critical factors and 3 critical chains were obtained by calculating the basic parameters of the complex network and analyzing the importance of nodes.Finally,the model was demonstrated through case studies and suggestions were made from the perspective of engineering practice.
