某超高层建筑电梯辅助疏散系统疏散模式研究

摘要

以某超高层建筑电梯辅助疏散系统为例,通过STEPS数值模拟软件研究多种楼梯、电梯混合疏散模式对提高超高层建筑内人员整体疏散效率的影响,分析电梯辅助疏散系统不同疏散模式的可应用性.将建筑分为4区段,设置不同的疏散工况,对比疏散时间,得出最优工况.针对疏散模拟结果提出提高疏散安全性的建议.%By the STEPS numerical simulation software,an eleva-tor auxiliary evacuation system in a super high-rise building was taken as an example to study the influence of multiple staircases and elevator mixed evacuation modes for improving the overall evacuation efficiency in a high-rise building.The usability of differ-ent evacuation modes of elevator auxiliary evacuation system was analyzed.The building was divided into 4 sections in the evacua-tion simulation and the evacuation time of different scenarios was compared to find the optimal scenario.Suggestions to enhance the safety of evacuation were put forward.
