摘要
介绍了疏散模型的分类,并考虑建筑模型、人的运动和基本参数建立了区域网格疏散模型。考虑人的行为的趋向性和人员密度对疏散速度的影响,给出人员移动速度的计算公式。以M ATLAB为工具开发了ZGESS计算程序。程序的图像显示区域可根据选择显示各楼层不同时刻下人员分布情况;模型参数、模型计算、模型显示三个按钮分别用来打开模型参数设置窗口、启动疏散处理运算、打开图像显示窗口;静态文本区域显示完成整个过程所用的总时间。
The classification of evacuation model was introduced and the zone grid evacuation model was established consider of building model, peoples movement and basic parameter. The formula to calculate the moving speed of people was put forward considered the trend of people＇s behavior and the effect to evacuation speed by density of people. The calculation program of ZGESS was developed based on MATLAB. The area to display the figure can show the distribution of people in different time according to the operation. The three buttons of parameter and calculation and display were to open the window for set the parameter and start the calculation of evacuation and open the window for display the figure. The total time needed to complete the whole process was displayed in static state text area.
