Bridge construction accidents are affected by multiple factors.It is of great significance to analyze and discuss the cou-pling relationship between risk factors for preventing construction accidents and ensuring the smooth progress of bridge construc-tion.In this paper,the N-K model is used to analyze 110 cases of bridge construction accidents at home and abroad from 1996 to 2023,and the coupling mechanism among four key factors:researchers,material,management and environment.The results show that the greater the number of risk factors involved in coupling,the more likely the risk will occur during bridge construction.Per-sonnel factors are the main influencing factors of bridge construction safety accidents,followed by management factors and mate-rial factors.The degree of risk coupling between personnel and management and personnel and material is large.In the process of bridge construction,the risk coupling between personnel and management or material factors should be avoided as much as possi-ble to cause serious multi-factor coupling.Based on this,this paper puts forward corresponding control measures from three as-pects:controlling key risk factor coupling,avoiding multi-factor coupling and preventing risk coupling from the source of risk,so as to provide reference basis and decision support for bridge construction personnel.
