摘要:	中文摘要 ? 台灣地區因中央山脈高聳縱列、河川多呈東西流向，故南北通行之交通系統均須跨越眾多河川，全國橋梁數目也隨交通建設的推動而與日俱增。由日據時期至今，台灣許多橋梁橋齡已經超過平均使用年限五十年之標準，公路橋梁百分之七十五橋齡在二十年以上，而縣道則幾乎全為二十年以上，由此可知台灣目前整體橋齡已有老化之傾向。本研究首先是針對國內橋梁演進特性作概述，並利用台灣地區橋梁管理資訊系統之資料庫作橋梁特性統計分析。另外，以既有之橋梁D.E.R檢測維修資料對國內橋梁劣化狀況作初步之統計分析，最後以資料採擷理論應用於橋梁資料庫之橋梁基本資料及檢測資料之統計分析，試著找出各種橋梁型式中，較常發生之劣化狀況與構件維修狀況，以作為橋梁管理機關日後對於橋梁之維修或補強之參考。本文統計分析結果可供國內橋梁相關檢測維修之初步了解。 ABSTRACT In Taiwan, the sum of bridges have greatly increased during advances of communication because the communication system, which is mainly collateral with the meridian line, has to cross the rivers which mostly flow along the parallel and to evade the high mountains in central area. From the period that Taiwan governed by Japanese till now, many bridges have been used over fifty years, which is the average ultimate expiration date. Besides, three fourth of the bridges on the high ways have been used more than twenty years. Moreover, those bridges on county roads almost have been used over than twenty years. In a result, the entire years of the bridges in Taiwan have a trend toward ageing. This research, first of all, is focused on the summary of advanced characteristics of bridges in Taiwan. Furthermore, gather statistics and analyze characteristics of bridges by using the database of the bridges management system in Taiwan. Besides, initially analyze about the inferior situations of the domestic bridges with the established bridges D.E.R inspection and maintenance data. Finally, based on data mining theory, apply this research to the basic data from the bridges database and the statistics of inspection data and attend to discover common situations of the inferiority and the component maintenance that correspond to all kind forms of bridges as the reference to mend and maintain the bridges for the bureau of the management of bridges in the future. The result of the statistics in this research can provide an initial introduction to the related inspection and maintenance of the domestic bridges on the roads as well.
