火災發生時,由於一般民眾對於火災無法有效預防以及即時的滅火,更沒有消防避難的觀念,一旦發生火災發生,往往都會造成嚴重的人員傷亡以及財務上的損失,從以往的火災案例中可發現,民宅最常引發火災就是電線老舊走火或著延長線使用不當,高耗電量電器用品,使用同一個延長線或多孔插座,這些都是容易引發電線走火。 本研究針對位於平鎮市承德路民宅延長線火災案例,利用FDS模擬火災發生的形況來探討發生火災時的危險性,並改變各種不同參數來分析民宅火場之變化,以電腦模擬火場各物理現象,針對溫度、CO氣體濃度、房門開口、隔間材質不同等參數的變化,以及人員達到火場喪生標準的影響參數來做模擬,進而利用這些資訊可以讓我們做好防火準備。
Fire accident often causes serious casualties and property losses due to the general public cannot prevent fire occurrence effectively and put off the fire timely, and no concept of fire refuge in the event of fire. According to the previous data of firehouses that building fire caused by short circuit of old electric wire is the most common case, for example: with extension cord used improperly, high power consumption of electrical appliances use the same extension cords or multi-socket, these are prone to lead to electrical fire This thesis selects a short circuit building fire occurred on Chengde Rd., Pingjen case for study. FDS software has been used to explore the risk of fire, and change various parameters to analyze the changes in the fire site. Numerical method employs various physical phenomena, including temperature, CO gas concentration, the door opening, compartment material changes in the parameters, as well as the effect on personnel to reach the critical point of fire death to do the simulation. The simulation result might be useful for the reference of fire prevention engineering.
