基于社会网络分析的北京市有限空间作业事故分析

Analysis of Confined Spaces Working Accidents in Beijing Based on Social Network Analysis

为探究有限空间事故的内在关联,防范事故发生,以北京市2006—2014年发生的50起有限空间事故为研究对象,提取事故发生区域和有限空间类型为分析节点,构建1-模和2-模网络数据,运用社会网络分析软件Ucinet,对社会网络中各节点及节点间的关系进行了量化分析,揭示了北京市有限空间事故的规律和演化特征,对网络中潜在的重要关系和变化进行了识别,获得了有限空间事故在区域、阶段、类型等方面间的关系,为科学采取事故防范措施提供了指导。

In order to research the intrinsic connection between the confined space accidents in Beijing and prevent confined space accidents, 50 confined spaces accidents happened in Beijing from 2006 to 2014 are studied in this paper. By use of the Ucinet software of Social Network Analysis, the quantitative analysis of relationship among the social network nodes is made based on the chosen nodes of accident occurring areas and the confined space typos, and 1 - mode and 2 - mode networks are also established. The rules and evolution features of the confined space accidents in Beijing are revealed, the potential important relations and changes are identified, and the relationships of confined space accidents about the area, stage and type are obtained. The results provide guidance for scientific accident prevention measures.
