Abstract: In order to study the fire risk of underground wholesale shopping malls,an underground wholesale shopping mall was selected as the research object. Through the investigation of the field data, three typical fire scenarios were set, including shop fire, stairwell fire and walkway fire. The fire model was established by FDS, and the smoke flow in the underground wholesale mall was analyzed. According to the fire risk standard, the dangerous time in different areas was determined. Based on this,the evacuation simulation was carried out by Pathfinder evacuation software. The results showed that people in the underground wholesale mall can't evacuate safely in case of fire. Combined with the present situation and simulation situation of the mall, the safety hazard is rectified to ensure the safe evacuation of people in case of fire,and the fire prevention and control measures are put forward.

Key words: underground wholesale mall, fire hazard, FDS, Pathfinder
