摘要:
目前国内城市轨道交通工程中超长区间隧道的防排烟系统设计,通常做法是设置中间风井,将着火列车和非着火列车分隔在两个独立的通风、排烟区段,以保证非着火列车乘客疏散不受到火灾列车的烟气影响.但中间风井的设置容易受到室外地面条件、区域管控、城市景观、工程投资等多方面因素制约,在工程实施中存在困难.通过理论分析、数值模拟的研究方式,从乘客疏散安全及人员逃生区空气洁净的理念出发,通过对隧道内疏散平台采取防烟措施,结合隧道内纵向排烟,给出了一种新型超长区间防排烟系统模式,从而取消了中间风井,供其他工程参考.
Abstract:
The design of smoke prevention and exhaust system of extra-long interval tunnel of domestic urban rail transit projects is usually based on setting up an intermediate wind well to separate the train on fire from the train not on train in two separate ventilation and smoke extraction sections so as to ensure that the passengers in the not-on-fire train will not be affected by the smoke in their evacuation.However,the setting of the middle wind well is easily restricted by many factors,such as outdoor ground condition,regional control,urban landscape,project investment and so on,so it is difficult to implement in the project.Based on theoretical analysis and numerical simulation,this paper studies the new scheme of smoke prevention and exhaust system in the tunnel with the idea of ensuring the safety of passenger in evacuation and eliminating the intermediate wind well,and presents a new model of smoke prevention and exhaust system in the extra-long interval tunnel,which can be used for reference in other projects.
