The thesis analyses and studies torsion and distortion and cross bending of arbitrary changed section continues box gird bridges . program about geometric nature and torsion and distortion of continues box gird bridge are compiled in microsoft visual c + + 6 . 0 language
并且在microsoftvisualc + + 6 . 0可视化环境下编写任意变截面连续箱梁的扭转分析程序，并对该程序进行调试。
Except from the above achievements , the paper adopts two kinds of computational methods to analysis and compare , one is the spatial fem , the other is the cross direction supporting frame method . the results are present which the spatial fem can relatively accurately reflect stress of the practical structure , and which in spite of being convenient , the cross direction supporting frame method can lead to error while determining dimension of the cross bending str ess
另外，还针对该桥箱室较宽的特点，分别采用空间有限元模型和横向支承框架法两种计算方法对横向弯曲问题进行了分析研究。结果表明：空间有限元模型能够较准确地反映出实际结构截面的受力特点，计算所得的结果基本符合实际情况。
