metro singleside slope tunnel fire ventilation mode
Aiming at the characteristics of long continuous downhill distance and large lifting height in the metro tunnel with singleside slope, taking the metro line of a city in China as the research object, a numerical calculation model on ventilation and smoke exhaust of train fire was constructed, and the accuracy of numerical calculation was verified by using the 1:20 model experiments. Considering the factors such as the location of train fire, activation mode of fans, section form of tunnel and other factors, the diffusion process of fire smoke and the smoke temperature and gas concentration above the evacuation platform were analyzed. The results showed that after the occurrence of train fire, the stations at both ends of singlehole and singletrack tunnel should activate two tunnel fans respectively, and the stations at both ends of singlehole and doubletrack tunnel should activate four tunnel fans respectively and execute the corresponding smoke exhaust and air supply mode to control the smoke in addition to activating the jet fans. Due to the larger heat loss and air entrainment in the singlehole and doubletrack tunnel, the smoke temperature, CO concentration and CO2 concentration were lower than those in the singlehole and singletrack tunnel. When the longitudinal ventilation was activated to control the smoke backflow, the smoke descendent effect in the downwind area was more obvious. The risk of downwind carriage area in case of fire at middle of train should be fully considered in the design of smoke control and exhaust, and the emergency response mode should be determined reasonably.
