摘　　要：通过分析辅助墩对荆州长江公路大桥南汊通航孔主桥的受力影响,探讨了辅助墩与高低塔斜拉桥结构受力的关系,分析了辅助墩设置的最佳位置,并提出了不设置辅助墩所面临的问题及相应的解决办法,可为同类斜拉桥的结构分析、设计提供参考。On the basis of analysis of influences of the subsidiary piers on the mechanical behavior of the navigable main bridge of Jingzhou Changjiang River Highway Bridge over the south branch of the River, this paper conducts a study of relationship of the mechanical behavior between the subsidiary piers and cable-stayed bridge with unequal height pylons, analyzes the best positions the subsidiary piers should be laid out, and points out the problems of not providing the piers for the Bridge and corresponding solutions to the problems. The results of the study and analysis herewith may serve as reference to the structural analysis and design of cable-stayed bridges of similar kind.
