Abstract:
In this paper, 3 layout schemes of ventilation channel of emergency rescue station of a railway tunnel, i.e. fans in main tunnel, intermediate ventilation channel in main tunnel and separated ventilation channel in rescue parallel heading, are studied and compared. The results show that: (1) The scheme, jet fans in main tunnel, is the optimum. (2) The separated ventilation channel in rescue parallel heading can be adopted when considering the influence of aerodynamic load of highspeed trains on jet fans. (3) The shorter the ventilation channel, the lower the cost and more convenient the construction when adopting intermediate ventilation channel in main tunnel.
Key words: railway tunnel portal, emergency rescue station, disaster prevention Ventilation, ventilation channel
