都市設施為確保都市機能運作的骨幹，亦為都市建設蓬勃發展時期重要角色，但也面臨地震、颱風等天然災害之威脅，此外近年來設施因人為因素導致失效的頻率、類型及受災規模有逐漸增加且威脅擴大趨勢，因此以歷史災例經驗學習，將為都市設施機能營運衝擊與防護之重要課題。由歷史災例統計，災害發生對城市機能營運衝擊影響甚大，主要原因為系統複雜性高、相互依賴程度增加，都將會間接增加都市設施營運負擔，往往單一設施失效可能導致他項設施服務中斷，都市機能營運、與救災應變將面臨挑戰，例如2015年蘇迪勒颱風帶來的短延時、強降雨、與12 級陣風，共造成全臺約 450 萬戶停電，創下當時歷年最嚴重紀錄;另2016年高雄美濃ML6.6地震造成變電所饋線跳脫電力中斷、自來水管破裂停水，部分災區無法短時間復原;2017年815大潭電廠停電事故則造成全臺17縣市八百多萬家戶電力中斷，間接導致交通號誌失效，下班通勤時段交通嚴重阻塞、加壓站與淨水場失效，部份地區無水可用等連鎖衝擊。本研究重點為都市設施歷史害案例分析，與事故後經驗研究，對我國都市設施災害的營運衝擊、脆弱度進行探討，研究結果可提供相關都市營運減災對策建議參考。

Urban infrastructure is essential facilities for urban to function normally. Once these facility was damaged by a hazard event, most of urban functions could decrease seriously. Furthermore, the impacts on social, economic, industry and commercial activities might extensively affect the society at both large scales of e time and space. Also urban infrastructure is aggregation of many facilities which constitute the backbone to make any city operational. For this reason, damage individual system could demonstrate chain effects and cause failures to related and connected systems, then leads to cascading disasters. The operation state and interdependency among urban infrastructure during a hazard event is therefore a major concern for disaster reduction of urban hazards. This study considered the characteristics of earthquake disaster management to collect the disaster case for facility failure during hazard event, and discusses the operational impact and vulnerability of urban infrastructure disasters. Therefore, the result of this study assistant the authority to make an intelligent decision for urban infrastructure disaster or resource management.
