| 摘 要： | 建立地铁区间通风及防排烟模型,分析取消地铁联络通道防火门对区间正常运营环境和火灾烟气控制的影响规律。结果表明:取消地铁区间联络通道防火门对区间正常运营的平均环境温度影响很小,约为0.3%~1%。取消防火门降低了区间排烟风速,但通过制定合理的烟气控制模式,仍可满足区间纵向临界风速的要求。基于环境控制理论,取消地铁区间联络通道防火门是可行的。

| Abstract: | The influence on normal operating environment and smoke flow when canceling the fire door of metro connecting bypass,was ascertained based on mathematical calculation method.The result shows that canceling the fire door of the metro connecting bypass has little influence on the average ambient temperature of underground section under normal operating conditions,which is about 0.3%~1%.It reduces the smoke flow speed in the section,when canceling the fire door.However,the longitudinal critical wind speed can still be realized by establishing a reasonable smoke control model.Based on the theory of environmental control,it is feasible to cancel the fire door of metro connecting bypass. |
