Abstract

To study the diffusion law of smoke and temperature at different fire locations in a subway station fire, the firing process under different scenarios is simulated by pyrosim. Taking Shixi station of Guangzhou Metro Line 10 as an example, a subway model is established to study the distribution and diffusion law of smoke when the fire source is located in the middle of the station hall, the side end of the station hall, the middle of the platform and the side end of the platform, and analyze whether the corresponding states meet the evacuation conditions of passengers. Evacuation shall follow the principle of 6 min, and the temperature at the height of 1.5 m from the ground on the evacuation route shall not exceed 60 ℃. The CO concentration shall not exceed 6.25 × 10−4 kg/m3. The results show that when the two factors of high-temperature gas flow and CO concentration are comprehensively considered, the most unfavourable position is ranked as follows according to the risk from high to low: middle of platform > middle of station hall > side of platform > side of station hall. Platform fire is less stable and more dangerous than station hall fire, and the impact of fire location on the smoke spread and personnel evacuation is closely related to building structure. The research results can provide a reference for fire fighting and escape strategies in subway station fires and can also provide a basis for the architectural design of subway stations.
