Construction of Accident Causal Model for Building Construction Project Based on Cumulative Effects
In order to enrich the theoretical system of accident causation,a building construction accident causation model based on cumulative effect is constructed from a new perspective of risk accumulation.By analyzing a large number of typical accident investigation reports,introducing the concept of complex systems,drawing on the proposed protective barriers and accident analysis levels of accident causation models,the accident causation factors at each level of accident analysis are i-dentified.From the perspective of complex system evolution,we analyzed the accident evolution process and system risk ac-cumulation process,proposed the trigger conditions of accidents,and constructed a causal model of house building construc-tion accidents based on the cumulative effect.The model is validated with a case study,and the results show that the model can systematically identify the causes leading to accidents,reveal the correspondence between accident evolution,risk accu-mulation,and system risk.,and reveal the inherent formation process of rish accumulation,which confirms the usability of the accident causation model based on the cumulative effect.This research provides decision-making basis for accident pre-vention and analysis at the current stage.
