城市轨道交通隧道事故通风网络动力匹配方法

Matching Network Power in City Track Traffic Tunnel Accident in the Ventilation

城市交通隧道由于分流及辅助隧洞的存在,形成了通风网络。针对不同的通风任务,隧道事故通风系统有不同的通风量及动力的需求,其气流组织具有多样性,构成的网络系统非常复杂。如何设计一种合适的通风系统适用全部的通风任务,成了城市交通隧道建设中必须认真研究和解决的问题。基于通风网络理论,论述了城市轨道交通隧道事故通风系统动力匹配方法,并以某轨道工程为例,对轨道交通事故通风系统设计进行了探讨。

The ventilation network can be emerged in the urban traffic tunnel due to the existence of branch and auxiliary tunnel.In view of the different ventilation tasks,tunnel emergencyventilation system has different ventilation rate and power demand.How to design a suitable ventilation system for all of the ventilation tasks becomes a problem that urban traffic tunnel construction must carefully study and solve.Based on the theorry of ventilation network,The power matching method for the emergency ventilation system in urban rail traffic tunnel was discussed.In addition,the design for the emergency ventilation system in rail traffic is analyzed by taking onerail engineering as an example.
