地下科研装置隧道工作井消防设计方案分析

Analysis of Fire Protection Design Scheme of Work Shafts of a Scientific Research Tunnel

硬X射线自由电子激光装置工程是一条总长3.1 km的地下科研装置隧道,共设置5个工作井,实现元件安装、管道传输、束流分配、束流收集和科学实验等功能。以四号工作井为例,从防火分区划分、疏散空间计算、建筑构造等方面深入分析该特殊功能隧道工作井的消防设计方案,以期为特殊地下建筑空间的消防设计提供思路及经验。

The Hard X-ray free electron laser facility project is a scientific research tunnel,which is 3.1km long,with a total of 5 work shafts which are used for component installation,pipeline delivery,beam distribution,beam collection and scientific experiment.Taking the No.4 work shaft as an example,the fire protection design scheme of the tunnel work shaft with special functions is analyzed in depth from the aspects of fire protection zoning,evacuation space calculation and building structure,which can provide ideas and experience for the fire protection design of special underground building space.
