Abstract In this paper, the basic principles of risk analysis such as acceptable risk criteria and definitions, the calculation methods for individual risk, societal risk, and environmental risk are introduced. Types of highway tunnel disasters and their proportion of casualties are obtained and the most two common highway tunnel disasters (fires and vehicle collisions) are determined by statistical analysis of highway tunnel disasters at home and abroad. Based on investigations of some highway tunnel disasters and fire accidents in Britain, the F-N curve of those tunnels is drawn by means of F-N acceptable risk criteria; the effects of traffic patterns, traffic capacity, lane width, and vehicles on the probability of tunnel disaster are then analyzed.
