基于DELAB的人群疏散仿真研究

Research on Population Evacuation Simulation Based on DELAB

以北京市某中学的一栋教学楼为研究对象,设计一套人群疏散仿真系统用于指导该中学的疏散演习。该系统基于DELAB仿真软件,采用粒子运动的基本原理、动态邻域和可视角基本原理、行人加减速基本原理,构建了三维教学楼模型和粒子运动的数学模型,通过DELAB仿真计算,再现每个人在每个时刻的疏散行为,实现了人群疏散仿真。仿真结果表明,上述系统能够切实地展示实际疏散过程,为同类情景下人员的安全疏散模拟与应急疏散预案的研究提供参考。

In this paper, a teaching building in a middle school in Beijing was taken as the object of study. A set of crowd evacuation simulation system was designed to guide the evacuation of the middle school. Based on DELAB simulation software, the basic principle of particle motion, the basic principle of dynamic neighborhood and viewing angle, the basic principle of pedestrian acceleration and deceleration were established. The mathematical model of 3D teaching building model and particle movement was constructed. By DELAB simulation, Evacuation at every moment, to achieve the crowd evacuation simulation. The simulation results show that the system can effectively display the actual evacuation process and provide reference for the research on the safety evacuation simulation and emergency evacuation plan for similar personnel.
