【摘要】 人员的疏散是目前防火防灾研究的热点,但是传统的人员疏散研究多集中于人群疏散的离散仿真及可视化显示,无法逼真地表现个体的疏散行为.从火灾时人员疏散的物理特点出发,考虑不同人在火灾情况下的行为特征,采取几何连续的疏散空间,可较准确地计算人员安全疏散的时间及路径;建立了建筑物、火焰和角色动画的三维模型,动态交互地模拟火灾疏散过程,仿真效果逼真.更多还原

【Abstract】 The study of crowd evacuation is of great significance in fire safety engineering.Traditional studies mostly focus on the global emulation and visualization of crowd evacuation and adopt a discrete evacuation space with little attention on the behavior of different persons.This paper firstly studies the response of each individual with respect to the surrounding environment and assumes the evacuation space is continuous,so we can calculate the evacuation time and path of each person more accurately.In addition,we establish a platform including realistic model of buildings,fire flame,actor animation,and finally simulate the crowd evacuation process dynamically and realistically.更多还原
