摘　　要：介绍单索面斜拉桥——乌江二桥对斜拉索力在主梁上传递的结构处理手法,本设计通过总结以往工程实例的成功经验,再经过多方面的分析比较,提出新的结构处理方式,解决了结构受力、施工难度、外观等多方面的问题。This paper presents the method for structural handling of the main girder of the single cable plane cable-stayed bridge of the Second Fuling Wujiang River Bridge on which the stay cable forces will transmit and specifically proposes several new ways of the structural handling in the design on the basis of summarization of previous successful experiences of bridge construction examples and analysis and comparison of various related aspects. The new ways proposed in the paper provide solutions to the problems, such as those of the structural behavior, construction difficulties and aesthetic appearance of the main girder of the bridge.
