摘要:	摘　要目視檢測為一經濟快速之橋梁檢測方法，而目前國內橋梁目視檢測主要採用DER&U之評估法：以橋梁構件之損害程度、損害範圍、與安全之相關性等目視檢測之結果來初步判定橋梁之狀況。但此DER&U目視檢測評估法原僅針對鋼筋混凝土橋所發展而成，對於斜張橋、懸索橋、拱橋等特殊橋梁，因其橋梁構件型式與鋼筋混凝土橋並不完全相同，故此目視檢測方法並無法適用。而當橋梁管理單位須對所轄橋梁執行定期之目視檢測時，無適用檢測標準之特殊橋梁亦造成橋梁管理單位之困擾。本研究之目的為對特殊橋梁中之斜張橋建立一套目視檢測標準。此檢測標準以鋼筋混凝土橋之DER&U法為基礎，建立斜張橋構件的分類與檢測之標準，以初步判定斜張橋橋梁之狀況。其中，由於斜張橋結構特殊且受力行為複雜，如何以目視檢測對斜張橋做正確之評估，為本研究最大之挑戰。本研究所建立之斜張橋目視檢測標準，亦可應用於目前國內各橋梁管理單位所使用之「臺灣地區橋梁管理系統」中，便於橋梁管理單位對斜張橋進行檢測及評估之工作，使此橋梁管理系統之資訊更加完整，系統功能更為完善。 Abstract DER&U method is one of the fast and economic ways to perform visual inspections for bridges. In the DER&U methodology,“D”stands for degree of deterioration,“E”represents extent of the deterioration,“R”implies relevancy to safety of the deterioration, and“U”depicts urgency for repairing of the deterioration. However, the DER&U method was initially developed for inspecting concrete bridges. For cable stayed bridges, cable bridges, or arch bridges, the DER&U method is not immediately applicable due to their components are different from that of the concrete bridges. This causes problems for bridge management agencies that need to perform periodical inspection tasks for all kinds of bridges. This research aims at developing a set of standard criteria for inspecting cable stayed bridges. Development of the criteria is based on the DER&U method. Some extra bridge components, such as cables and tower columns, are added to represent complexity of such bridges. Determining such extra components and their inspection criteria to properly represent conditions of the bridge are the major challenges in this research. The inspection criteria for cable stayed bridges developed in this research can be incorporated into the “Taiwan Bridge Management System” (T-BMS) that is widely used by bridge management agencies in Taiwan. The developed methodology thus enriches information and functions provided by the T-BMS.
