铁路隧道防灾及运营通风策略分析

Analysis of Disaster Prevention and Operation Ventilation Strategy of Railway Tunnel

随着我国铁路建设力度的持续加大,铁路路网得到了跨越式的发展,同时铁路隧道的防灾救援及运营管理的问题也出现了。分析铁路隧道救援疏散体系、火灾危害及特殊性,并从铁路隧道各类防灾及运营通风模式进行对比分析,认为应因地制宜,根据铁路隧道的规模,经济性、通风效果、气流特征等因素,合理的选用防灾及运营通风方式。

With the continuous increase of China’s railway construction,the railway network has been a leap-forward development,at the same time,the railway tunnel disaster prevention and rescue and operation management problems have also appeared in this paper analysis of railway tunnel rescue evacuation system The fire hazard and particularity,and from the railway tunnel various types of disaster prevention and operation of ventilation mode comparative analysis,it is considered that according to local conditions,according to the scale of railway tunnel,economic ventilation effect,airflow characteristics and other factors,reasonable selection of disaster prevention and operation of ventilation mode.
