Abstract Taking the Liuyanghe Tunnel on the Wuhan-guangzhou high-speed railway and the Xiaoshan
Tunnel on the coal transportation railway from West Inner Mongolia to Central China as examples, this
paper discussed the key technology of fire protection design for long railway tunnels. Meanwhile, this
paper analyzed the characteristics of fire hazard in long railway tunnels, such as: the fire grows
uncertainly and is prone to re-burning, the heat generated by fire is not easily distributed, the
temperature rises quickly with big smog, it is difficult for the rescue equipment and personnel to approach
ire scene, the indirect loss is great, and so on. And then, after analyzing the fire-extinguishing
mechanism and components of both high pressure water mist system and superfine dry powder self-
extinguishing device system, this paper respectively proposed the design parameters for both high pressure
water mist system and superfine dry powder self-extinguishing device system, used in disaster prevention
and rescue centers and used in equipment caverns of long railway tunnels. This study result can serve as
a reference, for the design of similar projects and for the revising of the book titled The Code for fire
Protection Design of Railway Engineering
