摘要

本文首先對脊背橋作一整體介紹，包含脊背橋之簡介及及依據規範作為結構分析和設計準則。再以台灣一個設計案例來說明脊背橋的設計原則和結構行為，更藉此案例來比較脊背橋與其他不同型式橋梁的力學行為和設計流程的異同；最後再就分析之結果作討論及建議。
本文用專業分析軟體TANGO和SAP2000程式作脊背橋分析研究，討論在不同載重組合下，脊背橋結構之內力及外置鋼腱之索力變化，並藉由內力檢核，以確認脊背橋之應力符合設計規範。

The first part of this thesis focuses on general introduction of extradosed bridge , including the historical review , structural analysis and design criterion based on the specifications. The second part analyzes a practical example designed by Taiwan engineers in order to illustrate the fundamental principles and structural behaviors of extradosed bridge .In this part a statically structural analysis is completed to show the differences of design flow chart between the traditiomal bridge and extradosed bridge . Finally , a discussion and suggestion is presented based on the results of the previous analysis.The professional software programs are used in this thesis to do the analysis. The variation of internal forces and cable forces under various load combinations have been studied. The envelopes of internal stress is drawn to ensure the stress which meet the requirements of design codes.
