The Application of Fire Risk Evaluation Method in Fire Safety Evaluation for an Underground Shopping Mall

In the guidance of the thoughts from fire safety engineering and according to the kinetic mechanism of the occurrence and development of fire and the technological principle of fire prevention and control, this paper preliminarily studies the application of fire risk evaluation method in the fire safety engineering of an underground construction. By determining fire security goal, performance criterion and key fire danger zone, this paper uses FDS software to carry out a fire and smoke spread computer numerical simulation and obtains available safe evacuation time; simultaneously, it obtains required safe evacuation time in this underground construction by using an empirical formula computation method. After a comparison of these two kinds of time, it puts forward 6 measures to control fire smoke, which can provide reference for the improvement of this construction's fire safety planning and design.
