摘　　要：该文从曲线连续钢箱梁的受力特点出发,对影响结构稳定性的几个重要因素进行了探讨。并结合工程设计实例,对城市高架中经常采用的曲线连续钢箱梁的倾覆稳定性进行了深入研究分析。最后提出了相关的设计思路与建议,对此类型桥梁的设计研究具有较为重要的参考价值。Starting from the mechanical characteristics of curved continuous steel box girder, several important factors influencing the stability of structures are discussed in this paper. Combined with the engineering design example, the overturning stability of curved continuous steel box girder frequently used in urban elevated road is studied and analyzed. Finally, the relative design idea and suggestion are put forward. The experience can be referred for the design and study of the similar bridges.
