摘要
采用实测统计法对人流密度、疏散速度和通行流量3个基础参数及其相互关系进行研究,分析参数特性及其在疏散设计中的应用,建立基础参数的关系模型。通过参数模型分析认为合理的疏散设计应当控制人流流量接近但不超过通道的峰值流量,保证水平通道内的人员密度不大于1.6人/m2的极限值,楼梯内的人流密度不大于2.5人/m2极限值。
Based on actual measurement and statistics of the safe- ty evacuation original parameters, three parameters, which are crowd density, evacuation velocity and crowd flow, and their correlations were stuied. The parameters＇ characteristics and applications in evacuation design were analyzed, and formulates models for evacuation parameters were founded. As a result of the parameter analysis, a rational evacuation design should control the max flow under the peak value, which means the crowd density should be below 1.6 persons per square meters in corridor, and 2.5 persons per square meters in stairs.
