Research on Campus Safety Risk Coupling Based on N-K Model

In order to study the coupling characteristics of campus safety risk, combined with 120 campus safety incidents in China from 2001 to 2024, the risk coupling analysis was carried out from four dimensions of personnel, management, equipment and environment, as well as three aspects of single factor, double factor and multi-factor, and the risk value of different coupling forms was calculated based on the N-K model. The results show that the more coupling risk factors occur, the more serious the risk consequences. Personnel factors and equipment factors are the main factors causing campus safety incidents, so the coupling effect of personnel and equipment factors should be avoided. Finally, this paper puts forward targeted suggestions from three aspects: controlling key risk factors, avoiding multi-risk factor coupling and managing risk sources, so as to provide theoretical reference and decision support for campus safety management.
