平顶山市高层建筑安全疏散技术研究

Research of safety evacuation for high-rise buildings in Pingdingshan

通过对平顶山市752栋高层建筑进行排查、调研,重点研究了逃生楼梯的宽度、数量、分布对人员疏散时间的影响,并采用计算机仿真技术模拟了不同场景下人员逃生情况。实验结果表明,逃生楼梯的数量与宽度均与疏散时间呈线性分布影响,可用疏散时间选取最佳契合点,而逃生楼梯的分布则优先选择部署在建筑物中部的方案,这样才能有效降低人员逃生的时间,提高逃生效率。此模拟数据可为建筑消防设计提供参考依据。

Through investigation of 752 high-rise building in Pingdingshan city, we made a research on the impact upon escape time of stairs width, quantity, distribution for the staff, and by using computer simulation technology to simulate the situation of escape in different scenarios. The experimental results show that the number and width of the stairs and escape time have linear distribution effect; the best fit of escape time should be selected. Only upon the escape stairs deployed in the middle part of the building can people reduce the evacuation time and improve the evacuation efficiency. The simulation data can provide reference for fire protection design of buildings.
