| 摘 要： | 对自行设计的公和双层独塔斜拉桥下部结构进行了空间有限元分析，有限元分析模型中对不同构件采用不同的有限单元，同时对不同单元之间的连接进行了有效的处理，分析结果表明，在桥墩和承台之间设置的薄壁结构，极大改善了承台与群桩的受力状态，在对桩基结构进行分析的基础上进行了优化设计；优化后，桩基结构应力分布更趋合理，节省了材料，减少了工程量，也进一步了降低了工程造价。

| Abstract: | The lower\|part structure of Gonghe double\|layer and single\|tower cable\|stayed bridge is analyzed by using space finite element method. In space finite element model, the elements of several kinds were used for different parts of the bridge. The connection between different elements has been treated effectively. The stress distribution of the support desk and the ground peg is improved due to setting the thin\|wall structure between the pier and the support desk. Based on the structural analysis, the pile foundation is optimized, and the engineering cost is reduced. |
