| 摘要(中) | 台中市位處台灣中部地區為一都會型城市，境內有為數不少之河川分佈，在都市公路運輸系統中，橋樑扮演跨越河川等障礙之重要公路聯繫設施。一般而言，道路發生阻絕常未造成嚴重之交通及公共安全影響，因其可藉四通八達之路網，即時疏運替代；唯橋樑設施不同，為跨越之構造物體並為道路之重要疏運節點，損壞時搶修時程費時，並往往會造成公共安全事件，故本研究針對台中市主要橋樑初步結構良劣進行評估並提供相對中長期維修補強之建議。 本研究「對象及範圍」係以台中市主要河川上之跨越橋樑，適度篩選對交通、生活影響較顯著且具代表性之橋樑進行調查分析研究，「檢視方法」採用一般使用之目視檢測方法，以D.E.R.&U(Degree、Extend、Relevancy及Urgency)評估準則將橋梁劣化情形依其劣化嚴重程度、範圍、劣化現象、橋樑結構安全性、服務性影響，及修復之急迫性等項目加以評判區分為四類，進而作為優先維護作業或修補時程之判斷依據，並針對不同良劣等級之橋樑提供「處理方式建議」。 本研究結果顯示在選定目視檢測的四十九座主要橋樑中，共有四座被制定為第四類－〝主要結構有顯著缺陷，可能有安全上之疑慮〞，需立即進行細部檢測必要時加以重建，以確保行車安全交通順暢及維持台中都會區緊急應變功能正常運作。 此外本研究亦包括對橋樑警示系統設置及其重要性之初步分析與建議，因其對未來橋樑管理安全處置及緊急救難因應扮演重要角色，並對目前國內橋樑修補時機、延壽技術及生命週期之研究提供相當必要之資料及參考依據。 | |||
| 摘要(英) | Taichung, located in
the central part of Taiwan, is a metropolitan area with a number of
rivers distributed throughout out the area. In the transportation
system, bridges play the role as the vital facility of road network.
Generally speaking, traffic jam hardly causes severe traffic problems or
jeopardy to public safety. A major metropolitan city like Taichung has
already built a well-organized road network that helps develope a
convenient transportation system for the people living in the area . Yet
there still lies weakness in metropolitan traffic constructions: the
bridges, for example, serve as the important traffic joints among the
road network, they tend to cause traffic accidents and severe time delay
when damaged. This study aims at the evaluation of structural integrity
of the main bridges in the city. Based on the results of the field
evaluation the bridges are classified according to their current
degradation levels. Finally, the author provides the mid-term and
long-term recommendations for the maintenance and repair work of the
studied bridges. The object and extend of this study based on the selected bridges that have specific range of width and length and the evident effects on public transportation and lives. The author adopts the methods of field inspection with the forms revised from the references. Using the regulation known as D.E.R.U (Degree, Extend, Relevancy and Urgency), this study later classifies the bridges into four categories. For the prioritization of repair work, the study evaluates the degree, extent and condition of the degradation, the safety of construction, effectiveness of service, then further determines the urgency of the repair works. This study eventually suggests the detailed inspection and/or immediate repair for the most severely decayed bridges in the study area. Moreover, this study contains the original analyses of the importance of the bridge alarm system, safety management, and related emergency rescue plan in the future. The thesis also provides the imperative data and references to the timing of the bridge repair, the techniques to prolong the life of the bridges, and the research of bridge life-cycle in Taiwan. | |||
