摘　　要：通过实体热烟试验和模拟分析相结合的手段,研究上盖车辆基地咽喉区与出入段线之间烟气运动的规律,合理确定出入段线与咽喉区之间不同尺寸的自然排烟口条件下的烟气控制情况。研究结果表明:为避免咽喉区和出入段线之间的相互影响,两者之间应设置自然排烟口等防烟分隔措施。当出入段线或正线不向咽喉区方向排烟时,沿轨道方向设置9 m长的自然排烟口,可有效防止烟气从出入段线进入咽喉区;当出入段线或正线存在向咽喉区方向排烟时,沿轨道方向设置13 m长的自然排烟口,可以较好地防止烟气从一侧向另一侧蔓延。By combining physical hot smoke experiments with simulation analysis,this study investigates the patterns of smoke movement between the throat arrangement of covered vehicle base and entrance/exit line,determines the smoke control conditions under different sizes of natural smoke exhaust vents.The research results indicate,measures such as natural smoke exhaust vents should be set up as smoke separation,to avoid mutual influence between the throat arrangement and metro entrance/exit depot lines.When the metro entrance/exit depot lines or the main line do not discharge smoke towards the throat arrangement,setting up a 9-meter-long natural smoke vent along the track direction can effectively prevent smoke from entering the throat arrangement from the metro entrance/exit depot lines;when metro entrance/exit depot lines or the main line do have smoke discharging towards the throat arrangement,setting up a 13-meter-long natural smoke vent along the track direction can effectively prevent smoke from spreading from one side to the other.
