摘要:	橋樑的功用是連絡因地形而隔離的不同區域，使其交通運輸得以順暢；然而，橋樑管理大多著重在維護技術的探討，對於如何讓橋樑發揮最大機能的管理決策，則受限於人力、經費，往往無法妥善達成。就橋梁的生命週期而言，除了在規劃、設計及施工等階段必須配合使用者需求及施工規範來興建外，如何在維護階段持續提供使用者安全、舒適的行車環境則是充分發揮設施機能的關鍵。本研究將技術層面之維護工作項目與管理層次之經濟性觀點加以融合，並配合目前橋樑管理組織之架構，提出一套生命週期成本評估模式以供橋梁管理者決策參考之依據。本研究應用統計分析之研究方法，針對目前國內橋樑維護管理程序及歷年經費支出資料整理進行探討。再透過橋樑結構特性、服務性能及環境條件狀況之分析歸納，建立橋樑維護工作之執行原則。最後，依照維護程度的不同，將維護工作項目分為預防性定期維護、修理及置換等項目，在考量維修頻率、維修時機及因維修之延誤所致用路人成本等條件下，建立專案層級橋樑維護管理生命週期成本評估模式。 The function of bridges that link regions apart from different landforms is have convenient communications. However, management of bridges is mostly focused on probing into maintenance. Strategy of management is usually restrained from human resources and expenses to maximize the function of bridges. For life cycle of the bridge, it must be built to conform with user’s need and construction standard when in the phase from plan, design to construction. Moreover, how to provide users consistently safe and comfortable driving environment in the phase of maintenance is the key to bring the function of bridges into full play. This article is merge maintenance tasks from the technologic level and economic view from the managerial level, fit in with the framework of the bridge management organization at present to propose an establishied model of life cycle cost that managers should decide in accordance with. The method of statistic analysis is applied to probe into management process of bridges maintenance and expenses over the year in our country recently. Then, it is set up the executive principle of bridge maintenance according to characteristics of bridge structure, function of service, and environmental condition. Finally, it is divided into regular preventive maintenance tasks, repair and repalcement by maintenance level. In the condition of the frequency, timing, and users’ cost caused by mainenance, it is established an estimatable model of life circle costs in the level of investigation to the management of bridge.
