論文中文摘要:台灣長期受地震、天災影響,導致各地公路、橋梁造成重大損害,交通隨時可能中斷,更阻礙了救援行動。而本研究首先收集國內外可動式橋梁、軍用橋梁和移動式伸降機等相關文獻,並考慮救災的艱困環境,發展新的橋型設計,作為對外連絡道路遭阻斷之臨時輕便橋。
橋梁模型利用簡易連桿組所組成的縮圖器加以改良並組裝,可節省組裝時間,便於搬運與收納,另於橋梁組裝中加入折疊橋設計概念,並利用剛體旋轉的概念搭設橋梁跨河,避免需於河道中施作橋墩而增加施工上的困難度。本研究製作實尺寸救災橋梁模型,進行靜態與動態實驗,配合有限元素軟體(MSC.Patran)對模型進行分析,與實驗結果做比較並深入探討。
論文英文摘要:Taiwan often suffered from natural disasters such as earthquakes and typhoons which cause serious damages of roads or bridges. Thus, traffic was disrupted, and rescue actions were retarded. In this study, I collected references related to movable bridges, military bridges and lifting platforms. Based on them, a new form of bridges for disaster relief was developed, which can be used as a temporary emergency bridge when the traffic in remote districts was disrupted.
In the proposed design, a simple assembly of linkages such as pantograph mechanism was exploited to quickly expand bridge bodies. This idea can save time for the installation of bridge and make the bridge easy to carry and store. In addition, the idea of foldable bridges was employed to rotate the bridge decks such that the bridge can span over a river without piers. In this research, we fabricated a real-size bridge model and then conducted static and dynamic experiments to check if the proposed bridge satisfies the design requirements. Also, the finite element software MSC Patran and Nastran was used to simulate the experiments. The comparisons between the experimental results and numerical simulations were used to evaluate the validity of the numerical model.
