摘　　要：斜拉桥由于主塔造型独特,常采用空间异型曲面结构,具有很强的景观效果,但设计难度大,采用传统2D图纸难以表达具体的设计意图。以某异型独塔斜拉桥为例,介绍该桥的总体设计,主桥采用BIM 3D建模正向设计,通过参数化建模和可视化设计,建立全桥模型并3D出图,提高设计和施工质量,为全寿命周期BIM应用迈出关键一步。Due to the unique shape of the main tower,cable-stayed bridges often adopt space special-shaped curved structures,which have a strong landscape effect,but the design is difficult.It is hard to express specific design intentions using traditional 2D drawings.Taking a special-shaped single-tower cable-stayed bridge as an example,the overall design of the bridge is introduced.The main bridge has adopted BIM 3D modeling forward design.Through parametric modeling&visual design,a full bridge model is established&3D drawing is used to improve the design&construction quality,which has taken a critical step for the full life cycle BIM application.
