The paper studies non-adaptive behaviors in crowd evacuation from the views of interaction between persons,psychology and sociology,including related theories,computational models and simulation principles.

本文从人与人的相互作用和社会学、心理学的角度,对人群疏散中“非适应性”行为”的理论、计算机模型、模拟原理等进行了较为深入的研究,并以具体实例说明了Bu ild ing Exodus软件在人群疏散模拟分析中的具体应用,为完善该研究方向的计算机模型和促进软件的开发提供理论和方法的指导。

The direct use of the original data about crowd evacuation from other countries would lead to incorrect conclusions and affect the evacuation of crowds.

针对直接利用国外的人群疏散基础数据进行我国公共聚集场所人群疏散的模拟将会产生不准确的预测结果、导致这些场所人员安全得不到保证的问题,通过对大量国内外相关数据的搜集、整理和分析,确定了6种基础数据是建立疏散模型和开发疏散模拟软件的必备基础,包括:人员类型和人群的组成、人员水平投影面积和形状、人员密度、人员行走速度、边界效应宽度和预动作时间;总结出获取基础数据的4种主要方法,即直接观测和录像观测、人群疏散演习、个体试验和问卷调查;并确定了可在现有资料中直接获得并使用的数据以及仍需要进一步研究确定的数据。

The paper discusses engineering calculation of evacuation time based on crowd dynamics,in order to correct the error and give some improvement to the existing calculation method a comprehensive calculation method is given,in which pre-movement factor and interaction factor are introduced.

应用人群动力学理论来研究人群疏散时间的工程计算问题,为解决现有计算方法的误差,合理引入疏散时间延迟因子和人员相互作用因子,提出了疏散时间的综合计算方法,该方法对现行的工程计算方法进行了改进和补充,并运用building EXODUS软件的模拟结果对综合计算方法进行了初步检验。
