摘要
上海长江大桥主通航孔桥采用桥跨布置为(92+258+730+258+92)m的双人字形塔双索面分离式钢箱梁斜拉桥。通过深入的静力分析、动力分析及总体稳定分析,对上海长江大桥主通航孔桥的结构体系选择、提高结构整体刚度的措施、结构的可施工性等方面进行研究,从而对上海长江大桥主通航孔桥的总体结构性能进行深入论述。
The main navigable span bridge of Shanghai Changjiang River Bridge is designed as a separated steel box girder cable-stayed bridge with double inverted Y-shape pylons, double cable planes and with span arrangement （92＋258＋730＋258＋92） m. On the basis of the deep-going analysis of the static force, dynamic force and overall stability of the bridge, the selection of the structural system, the measures for enhancing the global stiffness and the constructability of the structure are studied and accordingly the overall structural performance of the bridge are expounded.
