摘要
解析事故致因之间的关系图谱,厘清事故致因的共现特征,对于揭示建筑工程施工安全生产事故的发生、发展规律至关重要。收集近10年来300起典型建筑工程施工安全生产事故调查报告文本数据,通过对文本数据进行分词处理和特征项降噪,基于事故致因理论提取建筑工程施工安全生产事故致因要素;通过改进词频-逆文件频率(TF-IDF)算法,挖掘高权重事故致因关键词,构建可视化共现网络图谱,探究事故致因的共现规律;运用层次聚类分析方法,探究事故致因特征相关性,确定事故致因类团。结果表明:建筑工程施工安全生产事故致因具有显著的共现规律,部分直接致因与间接致因之间呈现出耦合共现特征,部分事故致因呈现显著的类团结构,可将共现致因联系起来作为“集群”风险进行重点防控。
It is very important for analyzing the relationship graph between accident causes and clarifying the cooccurrence characteristics of accident causes to reveal the occurrence and development law of construction safety production accidents in construction engineering.This paper collected text data of 300 typical construction acci⁃dent investigation reports in recent 10 years,and extracted the causative elements of construction safety produc⁃tion accidents by using word segmentation processing and feature item noise reduction on the text data based on the accident causation theory.Through improving the word frequency-inverse file frequency(TF-IDF)algo⁃rithm to mine high-weight accident causes,the paper built a visual co-occurrence network graph to explore the co-occurrence law of accident causes.Furthermore,the paper used the statistical method of co-occurrence analysis of hierarchical cluster analysis to explore the correlation of accident causal characteristics and determine the causal group of accidents.The results show that the causes of construction safety production accidents in con⁃struction engineering have a significant co-occurrence law.Some direct causes and indirect causes show cou⁃pling co-occurrence characteristics,and some accident causes show a significant group-like structure,and the co-occurrence causes can be linked as a cluster risk for key prevention and control.
