基于Evacnet模型的高层建筑电梯疏散特性研究

Study on Elevator Evacuation Characteristics in a High-rise Building Based on Evacnet Model

针对高层建筑多模式人员疏散问题,根据电梯疏散Evacnet模型,采用疏散软件Evacnet4对典型高层建筑进行电梯疏散模拟计算,分析不同电梯性能、楼层高度、人员分布的电梯疏散时间,研究电梯疏散效率的变化规律。模拟计算结果表明:当楼层较高或者疏散人数不多时,使用电梯疏散有助于提高总体疏散效率;反之,使用电梯疏散不利于总体疏散效率。该研究结果可为提出最佳电梯疏散楼层、人员比,提高电梯疏散效率,发展电梯和楼梯协同疏散策略提供依据。

In view of evacuation patterns from high-rise buildings, this paper uses evacuation software Evac- net4 to simulate the elevator evacuation in a typical high-rise building. Then,the paper analyzes the impact of elevator performance,building height and distribution of evacuees on the elevator evacuation efficient. The results show that evacuation using elevators helps to improve the overall evacuation efficiency from a high-rise building with few evacuees, and vice versa. The research provides basis for determining the best e- vacuation floors and fraction of evacuees to improve the evacuation efficiency, thereby making the best strategies of synergistic evacuation utilizing elevators and stairs.
