Optimization Research of Smoke Control System in Subway Station Fires
(0) In subway station fires, the most immediate threat to passengers life is not the direct exposure to fire, but the smoke inhalation because it contains hot air and toxic gases, so its important to research the efficient smoke control model. Respectively, the fires were located on the carriages of the train on the islandplatform layer and side-platform layer to simulate the smoke diffusion by CFD, effects of the different smoke control model have been compared. Comparing the results, the lowest efficiency of exhaust was the one which the exhaust fans were set on the same level of the hang wall, and then the one of exhaust fans setting on the top of the railway was better, the highest one, which the efficiency was raised up 8.3％ and 10％ in the island-platform and sideplatform, was the exhaust fans doubling setting on the top of the railway. The reasonable set of the hang wall and the exhaust fans was the key to raise the efficiency of exhaust and make mass fraction and temperature of smoke depress.
