摘　　要：针对封闭回廊的排烟问题,提出在回廊转角处增设排烟口的方案。定量模拟计算表明,在相同的排烟量下,该方案相对于均匀布置排烟口的方案具有更强的烟气控制能力,可大幅减少烟气向毗邻楼梯间蔓延的比例,并且在温升、能见度、烟颗粒浓度的控制上均具有优势。A discharge smoke programs about the non-uniform distribution of smoke vent of the closed corridors was presen- ted by increasing smoke vents at corridor comer. It was demonstrated to be an effective ventilation method relative to the uniform distribution of smoke vents with the same amount of smoke. This method can significantly reduce the proportion of smoke spread to adjacent to the staircase and has more advantages in temperature, visibility and smoke concentration control.
