Abstract:	台灣的橋梁管理已開始導入生命週期的觀念，以降低成本與延長橋梁的使用年限，使得橋梁維護格外地受到重視，目前橋梁維護管理單位常會遇到的問題是當橋梁進行檢測後，針對檢測的結果難以決定應對該橋採取何種改善策略，此時會有多種選擇出現，可考量維修、置換或重建，或者是維持現況繼續執行日常維護作業，目前尚無一評定的標準使得橋梁維護管理單位難以決定該採取何種選擇，有鑑於此故有必要建立一套評選模式以幫助橋梁管理單位做此方面決策之參考。本研究擬建立一套橋梁改善策略最佳化評選模式，以橋梁整體生命週期的觀點來衡量每座橋梁當下該採取何種改善策略（日常維護、維修、置換、重建）。本模式主要是透過計算橋梁各改善策略間生命週期成本之差異，以評選每座橋梁的最佳改善策略。另外考量在預算不足的情形下，以達整體效益最大為目標，對橋梁與改善策略間作排列組合並以橋梁綜合評估指標作優選，重新選擇每座橋梁的最佳改善策略，以利後續橋梁維護管理單位分析決策、編列預算與申請經費參考用。 The bridge management of Taiwan has already attend to the concept of the bridge life cycle, in order to lower costs and extend the service life of the bridge .That make the bridge maintenance gradually paid attention . The bridge administrative department have be confront with the problem is that what kinds of the bridge improvement strategy（maintenance、repair、replacement、rebuild）should be selected after visional measuring the bridge .That don’t have united criterion at present. This research is to establish optimization model that help the bridge administrative department make decision in the bridge improvement strategy. This research set up a bridge maintenance optimization model is base on the concept of the bridge life cycle. This model is compare with the different of the bridge life cycle costs to evaluate the best bridge maintenance strategy. Furthermore by the best of total benefits , the budget is not enough to evaluate the bridge ,，to reselect the best bridge maintenance strategy and bridges.
