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

Abstract

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.

Analysis and Research on Fire Risk of Electric Vehicle Charging and Swapping Station

“…Method of Numerical simulation. Although the smoke parameters of building fire, such as temperature, species concentration, velocity vary with the time, they meet the combustion and movement rules and can be decribed throuth field simulation [4,5]. Firstly, the mathematical model is built according to the equations of energy conservation, mass conservation, momentum conservation and chemical composition equilibrium.…”

“…Fire power is very important for fire model that can be expressed by heat release rate (HRR). Fire spreading, smoke height, teperature and heat radiation depend on HRR, which affects fire development, harzards and evacuation, so HRR is one of the important parameters for designing fire and evaluating risk [5,9].…”
