Abstract?Taking Nanjing Yangtze Ｒiver tunnel as a research background，this paper analyzed potential structural damage， personal injury and rescue difficulty caused by fire disaster inside tunnel，and established an emergency response procedure． A physical model was built by using fire dynamics simulation software PYＲOSIM． This model could calculate the influences of ventilation speed on the smoke spread speed ，smoke concentration and temperature during the fire． Then 3． 0m /s longitu- dinal ventilation speed was chosen as the barrier speed． At last，this article expounded effective methods for people evacua- tion，vehicle and equipment protection and on-site rescue during a tunnel fire． Key words?tunnel? fire? emergency program? n
