Special Fire Protection Design for the Enlarged Stair and Escalator Public Area of a Subway Station

Abstract

Objective With the continuous improvement of socio-economic situation, there are more and more special subway projects. Traditional fire protection codes and standards are difficult to meet the needs of some subway stations with special designs. Therefore, it is urgent to adopt more targeted new design methods to meet these challenges. Method Combined with the specific technical problems encountered in the design process of a subway station in Shenzhen, an in-depth analysis and summary is carried out. On this basis, a corresponding special fire protection design scheme is proposed. By using the fire dynamics simulation software FDS and the evacuation simulation software PathFinder, the design scheme is validated. Result & Conclusion The special fire protection design scheme of this station excels in fire safety and successfully passes the approval of the Ministry of Housing and Urban-Rural Development, verifying its scientific validity and feasibility.
