摘要:	近年來橋梁安全監測系統普受世界所注目，為了解橋梁之動態反應及異變警訊，乃於橋梁上安裝各類型感測器以取得結構反應及環境資料，進行長期分析評估工作。台灣相關政府單位也相繼於管轄內之橋梁規劃設置了各類型之監測系統，以期維護橋梁之正常功能及安全，降低災害發生所造成之社會成本付出。基於橋梁監測中心資訊管理之理念，配合網路科技之進步，遠端控制且集中化管理數量龐大之監測資料，統合所有橋梁之監測系統，達到有效之集中化管理目的，以降低管理人員之需求。基於上述目的，本論文針對整體橋梁監測資訊架構，規劃設計現地監測架構、中央處理架構、警報架構以及遠端查詢架構等四個模組。整體監測工作由中央處理架構內之控制系統，遠端控制各橋梁之現地量測動作，並接收監測資料儲存至監測資料庫，提供後端處理分析以及遠端管理者查詢資料來源，並透過警報架構規劃，有效且廣泛的將異變訊息傳遞至各相關人員，以達到即時監控之目的。文中並以南方澳大橋之監測系統為其示範，說明監測系統運作結果，並與微動試驗結果進行比對，探討監測資料之正確性，以提高監測系統分析之可靠度。 Nowadays bridge health monitoring system is attracting high attention in the world. For better comprehension of the bridge seismic response and abnormal precautions, various sensors are assembled to bridges to acquire structural response and environmental data to conduct long-term analysis and evaluation. Correlative government units in Taiwan are successively planning various types of monitoring system to maintain the regular function and safety of bridges, and lower social cost caused by disasters. On the basis of bridge monitoring center information system, we can remotely control and centralize numerous monitoring data of bridges and then integrate all bridge monitoring systems in order to reduce demand of personnel management. For achieving the above-mentioned, this thesis mapped out on-site-monitoring scheme, center-processed scheme, alarming scheme, and remote-inquiring scheme. The overall concept of monitoring management is to remotely control, obtain on-site bridge responses by the control system of center-processed scheme, and then store into monitoring database those measured responses, which are successively used for processing and inquiring by remote managers. Afterwards, for the sake of achieving real-time monitoring, abnormal messages are effectively and extensively conveyed to correlative personnel through alarming scheme. Finally, in order to explore the accuracy of monitoring data and enhance the reliability of monitoring system, the monitoring system of Nanfangao Bridge is illustrated and monitoring data is compared with its counterpart measured on the spot.
