Research on the Causes of Construction Safety Accidents Based on Complex Network Model
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.
