摘要

以雪山隧道發生2輛大客車追撞火災為研究案例，利用FDS軟體模擬隧道通風狀態以及固定式水系統滅火設備放射情形，搭配最不利之可能火災情境，探討隧道內人員可能面對的危險環境。研究發現FDS模擬火災的最高釋熱率發生在約8分鐘時。當隧道開啟通風排煙及固定式水系統滅火設備時，對於隧道本體以及隧道內部人員防護的效果最顯著。

The Hsuehshan Tunnel was used as an example for the simulation of two simultaneous bus fires inside a tunnel using a software program called Fire Dynamics Simulator (FDS). The worst case fire scenario was simulated in a manner whereby it would affect humans inside the tunnel. The aim was to obtain a better understanding of the fire environment in road tunnels. The simulation results showed that the peak of heat release rate of the simulated fire, which was created to involve two buses in the Hsuehshan Tunnel, occurred at around 8 minutes. When the ventilation and water based fixed fire fighting systems (WFS) were activated, these were found to provide the best protective effect for road users.
