摘　　要：选取某超高层写字楼,使用STEPS软件进行人员疏散模拟。按照建筑设计容量和人员密度计算各楼层的人员荷载。将楼梯、不同分布高度的电梯、避难层三种疏散设施相组合,设置5种疏散方案进行模拟研究,得出不同方案下建筑内部剩余人数随时间变化的曲线以及不同方案中由电梯疏散的人数占总人数的百分比,分析各疏散方案的疏散效率。研究结果表明,"楼梯+电梯+避难层"的组合为最优疏散方案,疏散效率和安全性最高。A high-rise office building was selected and the evacua? tion in it was simulated by STEPS. The personnel load of each floor was calculated according to the design capacity and the per?sonnel density of this building. With the combination of staircase, elevator of different height and the refuge floor,five evacuation?schemes were set in the research. The change of number of remain?ing person with time and the ratio of person evacuated from eleva?tor to total personnel were obtained to analyze the evacuation effi?ciency of different scheme.The results showed that the combina?tion of'stair+elevator+refuge floor'is optimal evacuation plan that has the highest efficiency and safety of evacuation.
