摘　　要：开敞营业厅式地下商业建筑内部空间借助店铺、货架和柜台的布置形成通道,内部空间为扁平大空间,且空间同质化严重,多条路径可通往安全出口,导致应急状态下人员难以对最短疏散路径做出判断,疏散效率得不到保障。本文运用仿真模拟软件,对开敞营业厅式地下商业建筑进行疏散模拟研究。研究旨在通过分析水平和垂直疏散空间对疏散效率的影响,探究应急情况下影响安全疏散效率的关键因素,并据此针对性地提出空间优化策略,以期为开敞营业厅式地下商业建筑空间设计提供有价值的共性参考。As an important part of modern urban commercial system,underground commercial buildings with open business hall often form channels through the arrangement of shops,shelves and counters in their internal spaces,which are mostly flat and large spaces.This design method aims to improve customers'shopping experience and the utilization rate of commercial spaces.However,while this spatial layout brings commercial benefits,it also raises a series of challenges in terms of safe evacuation.Space evacuation problems of underground commercial buildings with open business hall are important parts of fire safety.Because the underground space is different from the above-ground space,it is a kind of relatively closed space with weak lighting,ventilation and smoke exhaust system.In the event of a fire,it is more difficult to evacuate people only by emergency lighting.In addition,due to the highly homogeneous characteristics of the internal spaces,coupled with multiple channels leading to each safety exit,it is easy for people who are not familiar with the internal spaces of underground commercial buildings to find the evacuation direction in an emergency.Moreover,the fire department can not intuitively see the underground fire situation on the ground,the rescue is more difficult,and the economic losses and casualties caused by the disaster are more serious.All kinds of difficulties directly lead to the low efficiency of personnel evacuation and increase the potential risk of casualties.In order to effectively deal with this challenge,reduce the threat of disasters to underground commercial buildings with open business hall,and significantly improve the emergency evacuation efficiency,this paper selected a representative underground commercial building in Dalian as an example for in-depth analysis.By using evacuation simulation software to simulate the evacuation process under different emergency situations,the key factors affecting the efficiency of safe evacuation can be accurately identified,and in turn,the spatial functions
