地下车站建筑设计中的安全性与紧急疏散研究

Research on Safety and Emergency Evacuation in the Architectural Design of Underground Stations

从抗震、防火两方面入手,强调了地下车站建筑设计中的安全性,提出了抗震设计时,应先对施工现场的环境进行勘察,在此基础上确定设防烈度、选取地震动、计算地基地震反应力、验算抗震计算结构,同时在防火设计方面,还要从防火分区设计、防火墙与防火门设计、装修材料、防烟分区入手做好设计。此外,对地下车站建筑的紧急疏散方案进行了探讨,明确了设计中的注意事项。

Starting from two aspects of earthquake resistance and fire protection,the safety in the design of underground station building is emphasized,and the environment ofthe construction site should be investigated first in the design ofearthquake resistance,and on this basis,the intensity of fortification should be determined,the ground motion should be selected,the seismic response force of the foundation should be calculated and the seismic calculation structure should be checked.At the same time,in terms of fire protection design,we should also start with the design of fire protection zone,firewall and fire door design,decoration materials,and smoke protection zone.In addition,the emergency evacuation scheme ofthe underground station building is discussed,and the points for attention in the design are clarified.
