采用Building Exodus 4.0模拟软件,研究了某校园宿舍建筑火灾场景下的出口宽度,可用出口数目,可用疏散楼梯数目以及人员对出口的熟悉程度等对疏散的影响规律。结果表明,在出口宽度到达某一阈值前,所需疏散时间随其增加而减少,超过该阈值之后,继续增加宽度对所需疏散时间影响甚微;随着可用出口和疏散楼梯数目的增加,所需疏散时间逐渐减少;人员对出口越熟悉,所需疏散时间越短。
Building Exodus 4.0 simulation software was used to study the effect of evacuation on exit width, number of available outlets, number of evacuation stairs available, and personnel familiarity with exports under a residential dormitory fire scene. The results show that the required evacuation time decreases with the increase of the outlet width before it reaches a certain threshold value. After exceeding the threshold value, continuing to increase the width has little effect on the required evacuation time; as the number of available outlets and evacuation stairs increases, The evacuation time required is decreasing; the more familiar the personnel are to the exit, the shorter the evacuation time will be.
