Abstract
The Qiongzhou Channel tunnel, which is under construction in China, is taken as an example to study the evacuation of a train in a tunnel. Fire Dynamics Simulator (FDS) and Pathfinder software are utilized to simulate the fire spreading and personnel evacuation. When a fire broke out in the tunnel, the process can be divided into three stages according to the development of fire, which are carriage fire period, fire spread period, and tunnel fire period. The safety of people evacuation in different stages was studied. It has been found that when a fire occurs at the carriage center, people can evacuate to the adjacent carriages safely. In the event of a fire happens at the carriage end, high temperature and smoke would threaten the safety of passengers. If the fire train could drive to the emergency rescue station, it has been proved 200 s ahead to protect passengers than driving outside, and people can evacuate to safety area within the available safety evacuation time. The results show that it is necessary to have an emergency rescue station in the extra-long channel tunnel, and cooling equipment and fire-extinguishing installations should be equipped in carriages to ensure passengers safety.
