【 摘 要 】

In order to achieve that the expressway operation companies may manage itself by different levels, and avoid accidents effectively, establishing a risk assessment model for static risk sources is necessary. First, according to the result of surveying, the risk source units of expressway operation enterprises was divided, and the risk sources of each unit were identified. The list of risk sources was established. At the same time, the types of accidents that may be caused by all risk sources were analyzed. Secondly, according to the principles of practical operability and effectiveness, and the relevant laws and regulations of the state on accident grading, criteria for evaluating the severity of accidents and consequences was set up. Finally, the risk matrix for risk level determination of the risk source of the expressway operation enterprise was set up.
