Analysis of 89 tunnel fire cases including road tunnel,railway tunnel and subway tunnel in recent was performed.The distribution of causes of fire depends on the type and engineering stage of tunnel.Using fire inappropriate is the main cause for 3 types of tunnel when it’s on building.However,main cause of tunnel fire on operation depends on the types of tunnel.Fault tree analysis is used to get logic expressions for causes of tunnel fire. Based on the analysis of cause of tunnel fire,measures including management of both human behavior and materials in tunnel are proposed for consideration of study and design of tunnel fire protection.
