摘　　要：应用FDS+EVAC结合中庭式建筑工程算例,计算得出建筑物空间发生火灾后的空气流速、烟气运动、温度场等情况,通过Smokeview展示火灾的动态发展过程;针对人员安全疏散相关控制指标进行讨论,着重分析应急演练过程中人员疏散的可能性和有效性,发现演练过程中人员疏散可能出现的问题。探讨基于人员疏散计算机数值模拟技术科学合理组织和规划消防应急演练的技术方法。Based on FDS＋EVAC software,air velocity,gas movement and temperature field were dynamically simulated for fire case in atrium,and spread of the fire was vividly showed as 3D scene in Smokeview software.Then the relevant guideposts aiming at personnel evacuation was discussed and the possibility and effectiveness of evacuation during emergency drill were emphasized so as to find the potential problem.The logical and reasonable organization and plan method for fire-fighting emergency drill were probed into based on the numerical simulation of personnel evacuation.
