Abstract: In order to scientifically evaluate the fire safety resilience of the subway station system and reduce the impact of fire disaster, based on the trio spaces perspective, the cloud model was built to evaluate and analyze the fire safety resilience of the subway station system. Based on the physical, social and information spaces of the trio spaces, combined with the process attributes of resistance, resilience and adaptability of the dynamic evolution of resilience, the analysis framework of fire safety resilience of subway station system is constructed. A combination weighting cloud model for fire safety resilience evaluation of subway station system is established. The evaluation result of Shijiazhuang subway station was moderate resilience. Through the calculation of the SPSSAU obstacle degree model, the main obstacle factors are found. Finally, based on the perspective of trio spaces and case analysis, suggestions on improving the fire safety resilience of subway station system were put forward.

Key words: fire safety, resilience, trio spaces, subway station, cloud model, combination weighting
