高层建筑人员疏散行动时间的预测

The prediction of personal evacuate travel time in high-rise building

针对目前疏散模型忽略房间中障碍物对人员行动的影响,提出一种“L”型行动路线,对空间节点进行了细化,建立了完善、合理的疏散行动时间预测数学模型。以此为基础开发出了高层建筑人员疏散行动时间预测软件,通过实例计算和对比国外公式,证明了节点细化的正确和软件开发的成功。

Aiming at the influence of neglecting of chamber obstacle on personnel action in the egress model, the author puts forward a kind of ＂L＂ shape proceeding way, and compartmentalizes space nodes tinier, and establishes the more reasonable mathematical model of forecasting evacuate travel time. On the basis of it, the time forecast software of personal evacuate travel in high-rise building is worked out. By checking the results of this program against those of foreign formula, it has been proved that tinier nodes are reliable and software is available.
