摘　　要：地铁车辆基地排烟口设置位置对上盖物业的影响较大,分析地铁车辆基地排烟口可能的开设位置,采用数值模拟方法研究排烟口不同开设位置下烟气蔓延的影响因素及规律。研究结果表明:为避免车辆基地火灾烟气对上盖物业的影响,当排烟口开设在车辆基地顶部时,排烟口与上盖物业之间的水平距离不应小于13 m;当排烟口开设在车辆基地侧墙时,防火挑檐宽度不应小于4 m。Over development buildings is greatly influenced by the setting exhaust port of subway vehicle base ,The opening position of exhaust port of subway vehicle base is analyzed, the smoke spread rule and influencing factors is studied under the different opening position of the subway vehicle base exhaust port by the numerical simulation, the research results show that, in order to avoid the effect of the subway vehicle base fire smoke to the over development buildings, when the exhaust port is opened at the top of the subway vehicle base, the horizontal distance between the exhaust port and over development building should not be less than 13 m; When the exhaust port is opened at the side wall of the subway vehicle base, the width of the fire overhangs should not be less than 4 m.
