Study on Fire Ventilation Control of Subway Tunnel: A Case Study for Dalian Subway
Sustainability, 2022 During the actual operation of a subway company, only one ventilation-control scheme is considered in the emergency plan, without considering the specific location difference of the fire source. However, in the case of an actual tunnel fire, the best ventilation-control scheme and personnel-evacuation scheme are very different given the potential ...
