摘　　要：建筑物内行人疏散受时间和空间限制,各种出入口、通道和瓶颈错综复杂。依托既有建筑空间,设计了正常疏散人群下3种不同设施布局方案,估计了各方案不同瓶颈影响下的安全逃生最短时间,并建立了考虑设施布局和动态信息的建筑物安全疏散模型,并通过仿真,对比分析了不同方案间的疏散时间、区域密度的变化和疏散效率。研究表明,模型计算与仿真能够有效的估计不同设施布局下的行人疏散效率,进而为不同的设施布局方案的选取提供建议。Pedestrians escaping from the architecture are restricted by limited time and space. There are so many different exits, channels and bottleneck. Three kinds of facilities layout were designed to be initial schemes. The shortest escaping time was estimated by the different bottlenecks. Then, a safety escaping model based on the facilities layout and dynamic information was proposed, and the escaping time, area density and evacuation efficiency were analyzed by the simulation. The research indicates that by calculating and simulating the model can estimate the evacuation time for different schemes, and the result can provide some advices for facilities layout.
