To explore the safety risk of tower crane operation,deeply explore the characteristics of accidents,and clarify the causal mechanism of tower crane operation accidents,an improved naive Bayesian network structure based on Apriori algorithm association rule mining is proposed,the model is trained in a data-driven manner to improve the efficiency and accuracy of tower crane operation accidents reasoning.According to the diagnostic reasoning to explore the causal mechanism of the accident,combined with causal reasoning to analyze the development t...
