A new bridge structure cooperated by the single - towered cable - stayed structure and the rigid frame structure was presented. many aspects of jinma bridge are researched and analyzed, such as the design method, configuration of the superstructure, section choice of the tower, design and construction methods of the deep - water bases, the stiffness of the cooperated rigid frames, strengthening way in the tower. it is concluded that this new structure is the economical, aesthetic and suitable project for the large - span situation
主要內容和結論如下： 1 、提出了獨塔斜拉橋與兩側剛構相連接的新型協作體系斜拉橋結構形式，並對該橋的方案比選、設計思路、橋面系結構形式、塔柱截面設計、深水基礎的設計及施工方法、協作剛構的剛度選取、塔柱的直束加固等方面作了詳細地計算分析和比較。 -
From above analysis, the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big, the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers. the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement, but also make large influences on the stress of transfer plate and near floors, thus it is necessary to strengthen those floors
通過上述分析，得出以下主要結論：多塔樓結構存在頻率密集現象，各振型間耦聯效應明顯，地震作用計算應採用cqc組合原則而不能簡單地採用srss組合原則；非對稱多塔結構的振型中，扭轉作用明顯，平扭耦聯效應值得考慮；裙樓剛度對整體結構的抗震性能影響很大，非對稱多塔結構宜控制裙樓與塔樓剛度比在適宜的范圍；非對稱多塔易導致平面剛度分佈不均勻，結構扭轉效應不僅在豎向抗側構件中引起較大的扭轉內力，對轉換層樓板應力有較大的影響，且延續至相鄰樓層，對相應樓層均應採取相應的加強措施。 -
The golden horse bridge with t - shape rigid structure and single - tower cable - stayed bridge is taken as an example for the solution of vertical vibration differential equation through the presented boundary condition
