摘要
协作体系斜拉桥是一种较为新颖的斜拉桥的结构形式。对于工程中常见的独塔协作体系斜拉桥，本文从边跨与主跨、塔高与主跨的比值等设计参数着手，分析协作体系斜拉桥合理的布置形式，提出合理的取值范围，并对边跨有无辅助墩的普通斜拉桥与协作体系进行比较。
Cable stayed bridge of cooperative system is a relatively novel structure form of such bridge. For cable stayed bridge of single tower cooperative system often used in practice, this paper analyzes the reasonable form of this sytem in detail from the ratios of side span to main span and tower′s height to main span and recommends reasonable scope of parameters. Moreover, the paper compares the cable stayed bridges of cooperative system to normal cable stayed bridges with or without auxiliary piers in side spans, and provides reference for the design of such bridge.
