Scene Design and Simulation Analysis of Fire Accident in Underwater Tunnel

In order to reduce the risk of tunnel fire accident, determine the fire power of the tunnel disaster prevention and evacuation facilities set requirements, by means of tunnel fire risk analysis and accident characteristics summary of proposed safety criterion for the design of underwater tunnel fire accident scene, fire power and growth rate, smoke exhaust mode and smoke emission selection, number of evacuation and evacuation time standards and so on. Using FDS+EVAC to simulate and analyze the scene of fire process and personnel evacuation, in order to better help us identify fire risk, to develop in line with the actual project of disaster prevention programs, service in underwater tunnel construction and post operation.
