中文摘要
近年來隨著國際間多起捷運與地下鐵系統之火災事故,造成極大的人員傷亡,歸納其事件造成重大傷亡之主要原因在於煙控系統之操作失效或緊急運轉策略不健全。因此,本研究希望可建立一捷運車站性能式煙控與避難系統設計之標準模式,以期簡化煙控系統之操作與加強緊急運轉模式之不足。
於第三章,介紹新舊型捷運車站之差異比較與一般捷運車站之硬體系統設計標準,進而瞭解新型捷運車站之優點與必要性。於第四章,介紹月台層煙控系統之設計分析,說明定址式排煙之優點,並利用美國國家標準局(National Institute of Standards and Technology)建築物與火災研究實驗室(Building and Fire Research Laboratory) 研發之火災成長預測程式—CFAST與FDS (Fire Dynamics Simulator)火災模擬軟體做為輔助工具,預測火災之煙沈積速度,模擬捷運車站月台層發生火災時,捷運車站月台層之濃煙煙層高度沈降速率及煙層溫度分佈。
於第五章中針對捷運車站避難系統設計進行分析,運用美國NFPA130之規定並配合日本建築中心對捷運系統避難逃生時間進行討論與計算。最後,利用動態避難模擬分析(SIMULEX)針對新捷運車站月台層與大廳層之乘客避難進行模擬分析,觀察人群避難的狀況及計算乘客離開月台層之避難時間,並與NFPA 130之規定避難時間比對,評估各避難路徑之安全性。
本研究最終整合煙控與避難系統,完成最新型之捷運地下車站之緊急運轉模式,可作為日後實際系統設計之重要參考。
Abstract
Recently, several major incidents occurred in worldwide metro and subway systems due to inadequate or inappropriate emergency procedures.
In this study, the traditional and innovative metro underground stations were analyzed utilizity the CFAST and FDS computer program. A comparative study has been conducted to evaluate the smoke descending rate, and temperature distribution, etc with addressable zoned smoke control system.
Dynamic egress analysis was followed to validate the NFPA 130 which was taken as the design guidelines to evaluate the evacuation time using SIMULEX program.
Finally, the smoke management design and egress system was integrated, which warrants its qpplication in actual engineering designs.
