建筑工程施工安全生产事故致因的共现特征分析
Analysis of the co-occurrence characteristics of construction safety production accidents causation in construction engineering
摘要
Abstract
It is very important for analyzing the relationship graph between accident causes and clarifying the co-occurrence 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 analy-sis 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.关键词
