The Study Of Tunnel Fire And Fire Protection & Succor Safety System About Long Double Tube Road Tunnel

In this paper, based on the QINLING-ZHONGNANSHAN long double-tube highway tunnel, the rule of temperature field, pressure field and smoke distribution in a long highway tunnel fire is studied. On the basis of this, Safety system on the tunnel fire protection and rescue of the long Highway tunnel are discussed deeply.Firstly, the paper introduces the tunnel fire about its characteristic, cause, harm and status in quo of research in the world. According to the theoretical calculation and fire test, the rule of temperature field, pressure field and smoke distribution in a long highway tunnel fire is analyzed. Then, highway tunnel fire cause is discussed by Fault Tree Analysis(FTA) method, and the preservation maneuvers are presented. The construction of fire detection and control systems and the fire protection methods are discussed, and it is important that alarm/fire protection system must be in-phase in the tunnel fire. Taking the QIN-LING ZHONGNANSHAN long highway tunnel for example, this paper provides some control measures for fire disaster ventilation and scheme of rescue and evacuation. At last , based on those chapters, the safety system on the QIN-LING ZHONGNANSHAN long double-tube road tunnel fire protection and rescue of the long highway tunnel is established. By way of safety system engineering method analyzing, in this paper, the general safety system on the tunnel fire protection and rescue of the long highway tunnel is discussed. It is emphasized that safety system on the tunnel fire protection and rescue of the long highway tunnel must be established perfectly making up of some important subsystem, for example, fire-protection, fire-detection, fire-protection, ventilation-control and so on.
