Open publisher page 1 citations

Abstract

In order to study the effectiveness of ventilation and smoke exhaust system in subway station,taking a subway as prototype,the tunnel fire and platform fire in subway station were numerically simulated by FDS.The distribution laws of smoke temperature、concentration of CO、visibility and smoke layer height were obtained.The design security objectives of ventilation and smoke exhaust system of deep buried Metro station was analyzed,and the means and methods of the effectiveness assessment analysis was also explored.
