| 摘 要： | 斜拉桥结构复杂，需要考虑的因素多，在目前有关斜拉桥纯数学的优化设计方法还不成熟的情况下，可以根据一般的综合比较来选定斜拉桥的结构体系和型式，然后在宏观分析的框架基础上缩小搜索范围，进一步运用正交优选法进行各部分尺寸的优选。

| Abstract: | Cable-stayed bridges are very complicated, with many factors to be thought about. At present, pure mathematic optimal design methods for cable-stayed bridges are not matured. We can select the structureal system and structural style by general comparison, then reduce the selection scale on the basis of macroscopic analysis and carry on the optimal selection of structural dimensions of the bridge using orthogonal design method. |
