Aiming at the problems of unclear concepts of risk and hidden danger and unclear management interface in some units in expressway operation and safety management, the relationship between risk and hidden danger in safety production is discussed, and the control principles in the safety management of the two are further explained. On this basis, the two are organically combined, a double-prevention model of risk analysis and hidden danger investigation and control, and a method for further put forward the focus of hidden danger investigation and management based on the double prevention model are presented, and the application effect of the model is discussed using "bridge engineering'' as a case. The research shows that the use of expressway operation safety risk control and hidden danger control model can effectively guide the expressway operation safety management unit to carry out double prevention work, achieve the goal of moving forward the risk barrier, and prevent, so as to curb the occurrence of safety production accidents and improve operation unit safety production management level.
