摘　　要：以某大空间钢结构商业街类建筑为例,利用经验公式计算疏散时间,再运用SIMU几EX疏散模拟软件对建筑物进行仿真模拟,通过比对计算结果与模拟结果,得出如下结论:模拟数据结果是经验公式法预测结果的1.3-1.5倍;人员可以在34 min之内完成疏散;楼梯间的容量限制会导致人群运动速度会降低.建议采用高灵敏度探测器、加强安全防护、建立合理有效的疏散预案、强化管理等措施,预防紧急事故的发生.A large space steel structure of the commercial street building was used as an example,using empirical formula to calculate the evacuation time,SIMULEX was used to simulate the building evacuation simulation software.By comparing the calculation results with the simulation results,the predicted result from simulation is 1.3 times to 1.5 times of the result predicted by the empirical formula method.The evacuation can be completed within 34 min.The limitation of stairwell capacity will reduce the speed of movement of the crowd.It is recommended to use a high sensitivity detector to enhance the safety protection,establish reasonable and effective evacuation plan and strengthen management to prevent the occurrence of an emergency.
