In this paper, the three level fortification criterion, two stage design method and the elastic response spectrum theory are adopted, and the program of nba ( the program of nonlinear - aseismic analysis for beam bridge ) is used to calculate. through gathering, analyzing and calculating a lot of bridge design materials, this paper induces a simple way to calculate the relative displacement of the beam and the pier, and then according to the current design method, it concludes a better design principle of the supporting length of the beams. at the same time the dynamics is adopted to put forward the design method of the carrying capacity and the lengthen of prestress wire ( steel bar ) falling - off prevention structures of highway bridges
本論文採用三水準設防、兩階段設計方法、彈性反應譜計算理論，運用橋梁結構非線性地震響應分析程序nba （ theprogramofnonlinear ? aseismicanalysisforbeambridge ）進行計算；通過收集大量的實橋設計資料，經分析計算，歸納總結出計算上下部結構相對位移的簡便計算方法；並綜合國內外的經驗值，提出梁的支承長度se的設計原則；同時運用動力學突加荷載的原理，推導分析了預應力鋼絞線式（鋼棒連接式）落梁防止裝置設計承載力的計算方法和設計伸長量s _ f的取值；最後本文通過實橋計算，說明了落梁防止系統設計的方法。 -
It has also pounded the keys, devices, disposition of surveyed spots, measure method and procedures, data gathering and process ( relation with construction workmanship ), error analysis and adjustment, control precision and rules, mechanism and method of control, tables of records, results and discussion. after completion, the bridge has good behaviors in dead loads state, cable forces, shape style of main beam, stress and strain of concerned sections, displacements of the tower top, which assure the reasonable state of cables, main girder and towers, and safe under running, demonstrate supervision
通過課題研究與實橋運用，荊州長江公路大橋斜拉橋施工過程各狀態和成橋恆載狀態下，斜拉索索力、主梁線形、主梁關鍵截面應變、索塔塔頂水平偏位等關鍵項目的施工控制結果均滿足設計期望值的要求，滿足橋梁施工范圍的要求，大橋主梁線形流暢，斜拉索、主梁和索塔三大體系的受力狀態合理，橋梁結構安全可靠，大橋的監測監控取得了圓滿成功，並為該橋營運階段的長期監測監控奠定了良好的基礎。
