摘　　要：南京新庄立交桥是一座以多层、多跨以及分叉连续为特色的预应力混凝土曲线梁结构。在讨论曲线箱梁基本受力特征的基础上 ,研究了分叉连续曲线箱梁桥的分析方法 。Xinzhuang Flyover in Nanjing City is a PC curved box girder bridge, characterized by multi story, multi span and structurally continuous at the bifurcated parts. After reviewing the basic features of the curved box girder, the analysis methods for the continuous bifurcated curved bridge are studied. Some essential design points for the PC curved box girder bridge are outlined in the end.
