【摘要】:为客观评估复杂多层建筑物的人员疏散效率,以一个3层地铁站为例,用City Flow流微观人员疏散模型模拟不同疏散场景,量化分析人员分布情况、电梯操作方式、人员寻路行为3方面的场景设置变数对疏散结果的影响,提出楼层疏散效率概念,探讨多楼层建筑结构人员疏散过程中如何摆脱疏散场景设置的变数,客观评价建筑结构自身的疏散效率。结果表明:增加手扶电梯E3使疏散时间减少9.8%,让大多数人选择楼梯S2可减少16.9%的疏散时间;距离安全出口越远的区域受疏散场景调整的影响越大,整体疏散效率的提高取决于所有疏散通道之间的相互平衡和配合;楼层疏散效率能反映各楼层自身属性,是客观有效的评价指标。
[Abstract]:In order to evaluate the evacuation efficiency of complex multi-storey buildings objectively, taking a three-story subway station as an example, different evacuation scenarios are simulated with City Flow flow microcosmic evacuation model, and the distribution of personnel and elevator operation mode are quantitatively analyzed. This paper presents the concept of floor evacuation efficiency and discusses how to get rid of the variable of evacuation scene setting in the evacuation process of multi-story building structure. Objective evaluation of the evacuation efficiency of the building structure itself. The results showed that the evacuation time was reduced by 9.8% when E3 was added, and the evacuation time was reduced by 16.9% if most people chose stairs S2; The area farther away from the safe exit is more affected by the adjustment of evacuation scene. The improvement of overall evacuation efficiency depends on the mutual balance and cooperation between all evacuation channels. Floor evacuation efficiency can reflect the attributes of each floor and is an objective and effective evaluation index.
