为了研究在现代高层建筑火灾中应用电梯进行疏散的问题,基于电梯在火灾中安全使用的前提,提出了建筑物火灾情况下,采用电梯和楼梯进行人员疏散的综合评价方法。通过采用和建立相应的数学模型,计算应用二种模型的疏散时间,进而对高层建筑火灾疏散进行量化评价,并确定混合疏散方式的最佳疏散人数的比率。为建筑物的火灾安全逃生计划的制定提供重要依据。算例仿真表明了该方法的有效性。
In order to research the fire evacuation using elevators in mooern high-rise buildings ,under the prerequisite condition of relible use of elevators in case of fire, the method of safety assessment on fire evacuation using both elevators and stairs in high-rise buildings is proposed. The calculation of evacuation time of using both evacuation modes is conducted to quantitatively assess the safety performance of fire evacuation and to determine the optimal proportioning of the evacuees escaping from the fire by elevators and stairs. The proposed method provides an important basis for laying the occupant emergency' plan. Simulation experiments show the effectiveness of the presented method.
