摘要

台灣地區地狹人稠，地表交通運輸系統已無法負荷龐大之交通量，發展地下快捷運輸系統是最佳解決之道，六年國家建設中，對改善都會區交通有許多地下設施興建計劃，包括鐵路地下化、大衆捷運系統、隧道開挖及地下商業街，由於上述之空氣供給完全依賴人工通風系統，一旦發生火災，必須對巷道風向、風量及溫度分佈充分掌握，才能採取適當之緊急應變措施，使人員傷害及財物損失降至最低。本文回顧近年地下設施通風及火災模擬之相關研究，包括礦坑火災、隧道、捷運及地下鐵。文中分為通風及火災行為、管道中之熱傳導、熱空氣動力及列車運轉時管道之壓力變化等主題，各主題均有深入之剖析探討並建議未來研究方向，藉以提供研究人員參考，瞭解地下設施發生火災後，在通風系統引導下，氣流及熱流藉由管壁及空氣之傳輸，彼此之交互作用以及各種應變措施可能產生之結果。

The current ground transportation systems are not enough to support the heavy traffic in Taiwan. To overcome this problem, underground transit systems are the best solution. Many underground facilities include subways, mass rapid transit systems, tunnels and underground commercial streets are in the Six-Year-National-Infrastructure-Plan to improve the urban traffic conditions. Air supply mainly depends on the artificial ventilations system in the underground facilities. As a fire starrts, it needs to understand the direction and rate of air and temperature dstribution so the emergency ventilation and evacuation can be properly selected to minimize the damage. The paper reviews the ventilation and fire in the underground facilities of mines, tunnels, rapid transit systems and subways. The ventilation and fire behaviour, heat transfer in tunnel, heat aerodynamic and train passage pressure equations are presented and discussed in detail. Several research areas are also suggested to under-stand the behaviors of air and heat transfer in the air flow and wall, their interactions and the consequence of different emergency responses.
