摘　　要：南京六合新城龙池路跨滁河大桥主桥为100 m+85 m独塔混凝土宽箱梁斜拉桥,结构新颖,受力复杂.介绍该桥结构设计,建立三维空间有限元模型,对其成桥运营状态下主塔及宽箱梁的受力性能进行空间受力分析.结果表明,该桥设计合理,子结构在理论成桥状态下受力良好.New in style and complex in load sharing, the main bridge of Chuhe Bridge of Longehi Road in Luhe new urban area in Nanjing is a Broad Box Girder Cable-stayed Bridge with a 100 ＋ 85 meters span. This paper introduces the structural design of the bridge and proposes a three-dimensional finite element model aimed to anabyze the space load sharing of the load sharing performance of the main pylon and broad box girder. The results indicate that the design of the bridge is reasonable and the subsystems work well under theoretical completed bridge status.
