摘　　要：以某地下商业广场为例,根据规范确定所需疏散人数,采用BuildingEXODUS模拟人员疏散情况,得到疏散所需的时间为242s。根据模拟得到的拥堵位置,通过调整疏散出口的相对位置,增设一部疏散楼梯和加大疏散楼梯宽度等方法重新进行疏散场景设计。模拟结果表明,采用这三种方法均提高了疏散效率,疏散时间分别较原设计缩短了约8%、33%和15%。Take a certain underground commercial plaza as an ex- ample, the number of evacuees were identified according to fire code, people evacuation was simulated by BuildingEXODUS, and the evaluation time was identified as 242 s. Then as to the con- gestion point according to simulation results, adjusted the rela- tive position of evacuation exit, added an evacuation staircase and increased the width of evacuation staircase, and then simula- tion was made again. The results showed that it could improve the evacuation efficiency through these three approaches and the evacuation time was shortened by 8%, 33% and 15% respec tively compared to the original design.
