摘要： 运用Pathfinder 研究某高层建筑火灾人员安全疏散。首先模拟单楼梯、单电梯的单途径疏散，其次进行顶层优先疏散及避难层模式的楼梯-电梯联合疏散研究，并针对两种联合疏散策略采用不同人员分流的方法进一步优化。结果表明：在顶层优先疏散策略下，电梯最佳分离层会随每层人员数量的减少而下降；顶层优先疏散情况下人员分流优化后可以减少电梯空载的情况；避难层模式采用人员分流方法，可在不影响疏散效率的情况下根据实际情况合理分配中高部楼层乘坐电梯人员的比例。

Abstract:

Pathfinder is used to study occupant evacuation in a high-rise building. Firstly, evacuation only by staircase or elevator was simulated, and then a study on the stair- elevator joint evacuation including top-level priority evacuation and refuge floor modes was carried out, and the two joint evacuation strategies were further optimized using different personnel diversion methods. The results show that under the top-level priority evacuation strategy, the best separation floor will decrease with the decrease of the number of people on each floor; under the toplevel priority evacuation, the empty load of the elevator can be reduced after the optimization of personnel diversion; as the refuge layer mode adopts the method of diversion of people, the proportion of people can be reasonably allocated in the middle and high floors according to the actual situation without affecting the evacuation efficiency.
