摘　　要：以辽河特大桥为背景,借助有限元软件,对大跨径斜拉桥在不同体系下的力和位移等静力反应进行了详细的分析,给出了斜拉桥改善结构静力性能的塔梁约束方式。The thesis takes Liaohe River as study background. With the detailed analysis on the static performance, such as force and displacement, bridge under different systems has been done. Thus, tower＆ beam constraint, performance of the cable- stayed bridge, has been concluded. help of finite element software, a of the long - span cable - stayed which is able to perfect the static
