In order to clarify the risk transmission process of high-altitude operations, a quantitative analysis of the direct transmission relationship among risk factors of high-altitude operations is expected. Based on the decomposition principle, high-altitude operations are divided into four levels: construction operations, operating conditions, safety supervision, and organization management. The grounded theory is used to identify 24 high-altitude operations risk factors, and the social network analysis method (SNA) is used to build directed high-altitude operations. Operational risk factors are related to the network model, and the centrality, location and influence degree of each node in the network are analyzed. Research shows that the relationship between nodes in the network of risk factors for high-altitude operations is relatively close. Based on the directed relationship between risk factors, there is insufficient safety investment → safety supervision responsibility is not in place → safety protection facilities are not in place and safety education and training are not sufficient → Weak security awareness→violating operations are two key risk transmission chains; at the same time, illegal operations, lack of safety knowledge and experience, and insufficient implementation of safety supervision responsibilities are the key factors that determine the risk factors of high-rise operations and the network risk density; finally formulated based on the analysis results Risk management and control measures, thereby cutting off the connection between risk factors in the network, and providing a scientific basis for risk management and control of high-altitude operations.
