It contains simple database of the people＇s behavioral reaction and structure characteristic parameters of tunnel fireproofing. The model can be used to calculate the total evacuation time in various scenes when fire occurs in the different locations of the tunnel. Combined with fire simulation soft ware CFD- POENICS3.5, Tunev model can be used to calculate the fire danger coming time; by comparing with these two kinds of time, it can be used to assess the safety of the evacuation, and the evacuation process also have a dynamic demo. The simulation results show that the Tunev model can be used to predict the reliability of safe evacuation for people in tunnel fire and provide references for people＇s safe escape scheme. Some relevant concepts of the model were described and an evacuation simulation of a typical tunnel case, i.e. Xuefeng Mountain Tunnel was performed by using this model. And the model＇s validation and actual aoolication were also described.展开更多

Therefore, urban safety has become a critical issue, and disaster prevention and mitigation are also considered in urban development and infrastructure construction. When earthquake disasters occur, road networks play major roles in rescue activity for responding to urban damage. The urban-disaster prevention spatial system attempts to mitigate hazards by considering shelters, routes for evacuation and rescue and necessary logistics. A literature review shows numerous studies related to a disaster-prevention shelter survey before or after hazards, however, they are less concerned with the reliability of shelter evaluation. This study assesses shelter evaluation by considering road networks. The authors construct 10 selected indices individually related to road networks. Three integrated composite indices are established to explain planned-shelter risks using the Arc GIS diagram of a spatial concept of an urban-planning review process. The relationship between shelters and evacuation/rescue routes is important for disaster-prevention planning. This survey investigates the factors of road networks, fire engine rescue routes, fire station location and road/population density for vulnerability evaluations.展开更多
