采用理论计算和软件模拟的方法对地下商业建筑人员的安全疏散时间进行研究,并对两种研究方法进行了对比分析.分析结果显示:对于待疏散人数较大的地下商业建筑人员疏散行动时间主要受疏散出口宽度影响；理论计算与数值模拟两种计算方法误差仅为8.5s,两种方法均可对地下商业建筑人员疏散时间进行预测,但数值模拟能够更直观的反应人员的疏散过程、安全出口和疏散通道拥堵和瓶颈现象,更适用于地下商业建筑人员疏散方面消防优化设计.%The safety egress time of the occupants in the underground commercial building was studied by theoretical calculation and software simulation, and the two methods were compared. The results showed; the egress time was mainly affected by the width of the exit in the underground commercial building for a large number of persons; calculating error of theoretical calculation and numerical simulation was only 8.5s, the evacuation time of the underground commercial building could be predicted by each method, but numerical simulations could intuitive response personnel evacuation process, export and evacuation routes, congestion and bottlenecks, but also for aspects of underground commercial building fire evacuation optimization.
